[Visual Haskell 0.2] Installation to a directory other than standard fails

[unsilicon at nm.ru]

Hello all.

Attempt to install Visual Haskell 0.2 for VS2005 to a directory other than standard ‘c:\Program Files\Visual Haskell’ failed because some of the files were installed to a correct (specified in installer) location
and some other still went to ‘c:\Program Files\Visual Haskell’ and installation script failed to register the Visual Haskell plugin into Visual Studio. Please, fix this.
