+ The Title summary information property briefly describes the type of installer package. Phrases + such as "Installation Database" or "Transform" or "Patch" may be used for this property. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The Subject summary information property conveys to a file browser the product that can be installed using + the logic and data in this installer database. For example, the value of the summary property for + Microsoft Office 97 would be "Microsoft Office 97 Professional". This value is typically set from the + installer property ProductName. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The Author summary information property conveys to a file browser the manufacturer of the installation + database. This value is typically set from the installer property Manufacturer. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The Keywords summary information property is used by file browsers to hold keywords that permit the + database file to be found in a keyword search. The set of keywords typically includes "Installer" as + well as product-specific keywords, and may be localized. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The Comments summary information property conveys the general purpose of the installer database. By convention, + the value for this summary property is set to the following: +
+ "This installer database contains the logic and data required to install <product name>." +
+ where <product name> is the name of the product being installed. In general the value for this summary + property only changes in the product name, nothing else. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The Template summary information propery indicates the platform and language versions supported by the database. +
+ The syntax of the Template Summary property information is: + [platform property][,platform property][,...];[language id][,language id][,...] +
+ For example, the following are all valid values for the Template Summary property:
+
+
+
+ If this is a 64-bit Windows Installer, enter Intel64 in the Template summary information property. Note that an + installation package cannot have both the Intel and Intel64 properties set. +
+ If the current platform does not match one of the platforms specified then the installer will not process the + package. Not specifying a platform implies that the package is platform-independent. +
+ Entering 0 in the language ID field of the Template summary information property, or leaving this field empty, + indicates that the package is language neutral. +
+ There are variations of this property depending on whether it is in a source installer database or a transform. +
+ Source Installer Database - Only one language can be specified in a source installer database. Merge Modules are + the only packages that may have multiple languages. For more information, see Multiple Language Merge Modules. +
+ Transform - In a transform file, only one language may be specified. The specified platform and language determine + whether a transform can be applied to a particular database. The platform property and the language property can + be left blank if no transform restriction relies on them to validate the transform. +
+ This summary property is REQUIRED. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The installer sets the Last Saved By summary information property to the value of the LogonUser property during + an administrative installation. The installer never uses this property and a user never needs to modify it. + Developers of a database editing tool may use this property to track the last person to modify the database. + This property should be left set to null in a final shipping database. +
+ In a transform, this summary property contains the platform and language ID(s) that a database should have + after it has been transformed. The property specifies to what the Template should be set in the new database. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The Revision Number summary information property contains the package code for the installer package. The + package code is a unique identifier of the installer package. +
+ The Revision Number summary information property of a patch package specifies the GUID patch code for + the patch. This is followed by a list of patch code GUIDs for obsolete patches that are removed when this + patch is applied. The patch codes are concatenated with no delimiters separating GUIDs in the list. +
+ The Revision Number summary information property of a transform package lists the product code GUIDs + and version of the new and original products and the upgrade code GUID. The list is separated with + semicolons as follows. +
+ Original-Product-Code Original-Product-Version ; New-Product Code New-Product-Version; Upgrade-Code +
+ This summary property is REQUIRED. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The CreatingApp summary information property conveys which application created the installer database. + In general the value for this summary property is the name of the software used to author this database. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The LastPrintTime summary information property can be set to the date and time during an administrative + installation to record when the administrative image was created. For non-administrative installations + this property is the same as the CreateTime summary information property. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The CreateTime summary information property conveys when the installer database was created. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The LastSaveTime summary information property conveys when the last time the installer database was + modified. Each time a user changes an installation the value for this summary property is updated to + the current system time/date at the time the installer database was saved. Initially the value for + this summary property is set to null to indicate that no changes have yet been made. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The Codepage summary information property is the numeric value of the ANSI code page used for any + strings that are stored in the summary information. Note that this is not the same code page for + strings in the installation database. The Codepage summary information property is used to translate + the strings in the summary information into Unicode when calling the Unicode API functions. The + Codepage summary information property must be set before any string properties are set in the + summary information. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ For an installation package, the PageCount summary information property contains the minimum + installer version required. For Windows Installer version 1.0, this property must be set to the + integer 100. For 64-bit Windows Installer Packages, this property must be set to the integer 200. +
+ For a transform package, the PageCount summary information property contains minimum installer + version required to process the transform. Set to the greater of the two PageCount summary information + property values belonging to the databases used to generate the transform. +
+ The PageCount summary information property is set to null in patch packages. +
+ This summary property is REQUIRED. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The WordCount summary information property indicates the type of source file image. If this property is + not present, it defaults to 0. Note that this property is stored in place of the standard Count property. +
+ This property is a bit field. New bits may be added in the future. At present the following bits are
+ available:
+
+
+
+ These are combined to give the WordCount summary information property one of the following values
+ indicating a type of source file image:
+
+
+
+ Note that if the package is marked as compressed (bit 1 is set), the installer only installs files
+ located at the root of the source. In this case, even files marked as uncompressed in the File table must
+ be located at the root to be installed. To specify a source image that has both a cabinet file (compressed
+ files) and uncompressed files that match the tree in the Directory table, mark the package as uncompressed
+ by leaving bit 1 unset (value=0) in the WordCount summary information property and set
+
+ For a patch package, the WordCount summary information property specifies the patch engine that was used + to create the patch files. The default value is 1 and indicates that MSPATCH was used to create the patch + A value of "2" means that the patch is using smaller, optimized, files available only with Windows Installer + version 1.2 or later. A patch with a WordCount of "2" fails immediately if used with a Windows Installer + version earlier than 1.2. A patch with a WordCount of "3" fails immediately if used with a Windows Installer + version earlier than 2.0. +
+ This summary property is REQUIRED. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The CharacterCount summary information property is only used in transforms. This part of the summary + information stream is divided into two 16-bit words. The upper word contains the transform validation + flags. The lower word contains the transform error condition flags. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ The Security summary information property conveys whether the package should be opened as read-only. The database
+ editing tool should not modify a read-only enforced database and should issue a warning at attempts to modify a
+ read-only recommended database. The following values of this property are applicable to Windows Installer files:
+
+
+
+ This property should be set to read-only recommended (2) for an installation database and to read-only + enforced (4) for a transform or patch. +
+ Win32 MSI APIs: + MsiSummaryInfoGetProperty, + MsiSummaryInfoSetProperty +
+ This property queries the database every time it is called, + to ensure the returned values are up-to-date. For best performance, + hold onto the returned collection if using it more than once. +
