PRB: After installing Visual Studio 2012, XLL+ for earlier versions of Visual Studio is broken

Problem

After installing Visual Studio 2012, XLL+ for VS 2005, 2008 or 2010 no longer works. Whenever I try to create a new function or amend an existing one, I get the following error:

System.Runtime.Serialization.SerializationException: Unable to find assembly 'Psl.XL7.FunctionModel, Version=7.0.3.102, Culture=neutral, PublicKeyToken=b753a985dcbde9e1'.

I also get a linker error LNK1123 when building a project which built perfectly before I installed Visual Studio 2012:

        LINK: fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt
        

Resolution

This issue is fixed in XLL+ 7.0.4, so the best solution is to upgrade to XLL+ 7.0.4. If you using Visual Studio 2010, then you should also apply Visual Studio 2010 SP 1.

If you are unable to upgrade to XLL+ 7.0.4, then follow the alternative instructions below.

For users of XLL+ 7.0.3

Note: These instructions and Patch F00156 are only for users who cannot upgrade to XLL+ 7.0.4. Everyone else should simply upgrade to XLL+ 7.0.4.

1. You should apply the patch file listed below.

2. If you are using Visual Studio 2010, you should make sure that you have applied SP1.

If you have a earlier version of XLL+ 7 installed, you should visit our download page at http://www.planatechsolutions.com/support/download_front.aspx and download and install the version 7.0.3 of XLL+.
