Hello Artemza,
The logs point to Admin privilges. However this is strange that, you are able to install the 32-bit setup and not the 64-bit on the same machine. You may like to check the persmissions on C:\Program Files\ folder.
Alternatively, you can try the following steps:-
- Launch Command prompt as Administrator
- Navigate to the installer location and type the name of installer with extension followed by -console and press enter. For eg ColdFusion_10_WWEJ_win64.exe -console
Hope that helps.
Regards,
Anit Kumar
