Thanks very much for Phil's answer.
Hi Peter,
Thanks for your post. I am Hongye Sun [MSFT] and it is my pleasure to work
with you on this issue.
This is a by design issue. As Phil's said, the RemovePreviousVersions
behavior changed in VS 2008, and that made updates version based. The
update rule is called File Versioning Rules. It is documented at
http://msdn.microsoft.com/en-us/library/aa368599(VS.85).aspx.
The installer will make the determination to copy the files depending on
following properties:
- Version
- Date
- Language
If both files have version, by default, the logic of replacement of file is
documented at
http://msdn.microsoft.com/en-us/library/aa367835(VS.85).aspx
The rule is defined by REINSTALLMODE property in MSI. It is documented at
http://msdn.microsoft.com/en-us/library/aa371182(VS.85).aspx.
Based on these, following are the possible workarounds:
1. Update file version manually
Increase Project properties -> Assembly Information -> File version before
building a setup package.
2. Update file version automatically
Visual Studio setup project does not support it natively. One possible way
is to use MSBuild target to achieve it. Here is an existing tool for you to
reference:
http://code.msdn.microsoft.com/AssemblyInfoTaskvers/Release/ProjectReleases.
aspx?ReleaseId=232
Note: Each of the 4 numbers in the Version string is limited to 65535. You
may need to change the default target file.
3. Change REINSTALLMODE property default value in MSI file
Download ORCA tool from
http://blogs.msdn.com/astebner/archive/2004/07/12/180792.aspx.
Use ORCA to open the target MSI file and add following name and value pair
into Property table:
REINSTALLMODE = amus (omus is default value)
This value will force all files to be reinstalled, regardless of checksum
or version. For detail, please refer to
http://msdn.microsoft.com/en-us/library/aa371182(VS.85).aspx
Please feel free to contact me if you have any question. Thanks.
