Howto downgrade from ICC 11.1.038 to 10.1

[simbalee]

I have reported bugs of ICC 11.1.038 here. It seems that the bugs wont be fixed within some weeks. Therefore I decied to downgrade to 10.1 beause it had no problem for compiling the same project.

However, it turns out that the project file (xxxx.sln) can not be open with VS2005.
It is said the ICPROJ file was created by a newer version of ICC ( 11.1.038), hence it can not be opened with the older version. And I do not have backup of SLN & ICPROJ generate with older version of ICC.
So, can anyone tell me howto downgrade ICC and use project file made by newer oversion of ICC?

If not already installed, you can istall Intel C++ compiler 10.1 but need not install Visual Studio IDE integration for 10.1.

Youcan select different Intel C++ compiler version from IDE Tools -> options ->Intel C++ -> compilers.

The following might work:

1) With Intel 11 installed convert the ICC project back to MS.
2) Uninstall 11 (or even leave it installed if you want to bounce between the versions).
3) Install Intel 10
4) Convert the MS project to Intel for use with version 10.
