I originally posted this in the "Where is the Forum For…? " forum and it was suggested trying here:
I'm assuming this error is caused by the way I have IIS setup or by the way I'm building the project or the MSI setup, but not sure so not sure where best to post it. I did post it to the IIS forum 2 weeks ago but received no response other than to verify
the setting for Enable 32-Bit Applications".
I have a VS2010 web service project built using "Any CPU" platform and installed via an MSI setup whose target platform is x86. I am trying to test the install on a laptop running Win7 x64 with IIS 7.5.7600.16385 on the default app pool. IIS6 Management Compatability is turned on and the x64 version of the Framework is registered. The ISAPI and CGI restrictions are set to ALLOW for all versions of .Net (v2.0.50727 and v4.0.30319)
In IIS, the application pool default "Enable 32-Bit Applications" is set to TRUE.
When I execute the MSI, it rolls back with the message "The installer was interrupted before the application could be installed". Running the msiexec with logging provided these conflicting error messages:
ERROR : The error indicates that IIS is in 32 bit mode, while this application is a 64 bit application and thus not compatible.
AND
ERROR : The error indicates that IIS is in 64 bit mode, while this application is a 32 bit application and thus not compatible.
I'm not sure how IIS can be in both 64 and 32 bit at the same time, while the application is in the opposite mode of IIS in both cases as well???? The previous VS2008 version of this MSI install works with the current IIS setup.
I've even tried building the solution and the msi as all x86 or all x64 but that still results in the same error messages. I've also run our previous msi install built under VS2008 with msiexec logging and compared the output files so I can see this is where it goes off the happy path. The VS2008 install works, but not VS2010. The VS2010 MSI was created from scratch after we upgraded the original msi to VS2010 and originally encountered this error.
Thank you for any help or ideas!
