Error when installing Studio 2015

Hello, I can't install my version of Trados 2015 on my new laptop: following message shows :
"Setup has detected that the file 'C:\Users\[username]\AppData\Local\Temp\VSDC554.tmp\VCRedist2005SP1-KB2538242\vcredist_x86.exe' has changed since it was initially published.
See the setup log file located at 'C:\Users\[username]\AppData\Local\Temp\VSDC554.tmp\install.log' for more information."
I also tried to manually install Visual C++ to no avail, and tried different solutions read on Community posts ; none worked.
Does anyone have a solution ? Many thanks!
