can't compile any new indicator / robot

Hello all,

I have  a problem which occurs right at the beginning of compiling an indicator or a robot. I get always the error message:

Error: Invalid search path 'c:\program files(x86)\Microsoft Visual Studio\VC98\lib specified in 'LIB environment variable' -- The system can not find the specified path.'

I hadn't that problem before. I was able to compile my source code. I did some deinstallation of other programs and I am wondering whether cAlgo is missing some standard Microsoft libraries now. I also did a reinstallation but that doesn't help.

Do you have any idea to help me out of this mess. Thank you very much in advance.

Kind regards, Hugoman
