Installation problem on new laptop - .exe file has changed since it was initally published

I'm trying to install Trados 2015 on my new laptop and get this error message:

Setup has detected that the file 'C:\Users\xxxxx\AppData\Local\Temp\VSD7022.tmp\VCRedist2005SP1-KB2538242\vcredist_x86.exe' has changed since it was initially published.

See the setup log file located at 'C:\Users\xxxxx\AppData\Local\Temp\VSD7022.tmp\install.log' for more information.

Please help.
