--- Comment #4 from Yolande Haneder yolande@haneder.biz 2007-08-29 13:51:07 --- I am now able to replicate the problem with another component of Visual C++ 2005:
vcredist_86.exe
It seems that the file vcredist.msi is unable to install and throwing the same error.
(Just a note so that you don't have to the whole Trados installation procedure to see the error message).
