I have read several posts about the configuration manager in VS2010 (or before) but I can not find my problem.
I have a solution containing 6 projects.
When I open the Configuration manager, I can select:
‘Active Solution Configuration’ with values Debug, Release, New or Edit.
Áctive Solution Platform’ with values Any CPU, Mixed platforms, x64, x86, New or Edit.
And for any of my 6 projects the configuration (Debug, Release, New, Edit),
Platform (non startup projects: Any CPU, New, Edit and startup project: x64, New, Edit).
For all projects except the startup project the only (real) choice for Platform is ‘Any CPU’, which I think is fine.
However, for the startup project I only can select x64 so I assume running it on 32 bit Windows OS’s will be a problem?
I have played in history a bit with the values and now somebody mailed me this error he gets:
the version of this file is not compatible with the version of Windows
you’re running. Check your computers system information to see whether
you need an x86(32-bit) or x64 ( 64bit ) version of the program, and
then contact the software publisher
(also when I select the x86 platform I only can select x64 as platform in my startup project, while others are set to ‘Any CPU’.
When trying to add Any CPU to the startup project, I can select it but it asks to copy the settings and I only can select x64 or empty. Selecting either of them results in the error:
This platform could not be created because a solution platform of the
same name already exists.
I assume it was previously set to x86 but I’m not sure, anyhow, how can I get the ‘Any CPU’ selection back for my startup project?
UPDATE: SUDDENLY I COULD ADD THE OPTION ‘ANY CPU’ WITHOUT GETTING AN ERROR.
So my problem is solved …
I only don’t know why it didn’t work the first time … I just closed the window and started it again and it was possible.
You can add the platform back in the solution configuration manager.
Right-click solution -> Properties… -> Configuration -> click “Configuration Manager…”
Now the problem project’s platform says “x64”. click its drop-down arrow, New…, Any CPU – copy from x64.
Uncheck the “Create new solution platforms” checkbox on the New Project Platform dialog
