Hi,

If by chance you install version 2.3.5 on a 32-bit system, the 
installation will succeed, the software will work without any error 
message but the result of the calibration process will be wrong 
(strong red dominance).

This version is for 64-bit systems only.

The big issue with this is that uninstalling the software (and the 
drivers through the Device Manager) will not be enough. Version 2.2 
and 2.3 will no longer work because they'll still try to work with 
the new driver (spyder2.sys) instead of the old one (cvspydr2.sys).

If you are familiar with the registry information that is related to 
drivers in the registry and with the management of INF files, you can 
try to manually fix the problem (this is what I did). Otherwise, 
you'll never run version 2.3 or 2.2 again.

So the installer should check whether it is run on a 64-bit system 
and abort otherwise. Given the consequences of such an installation, 
the developer of the installation package should have added this test 
to his code. Again, a big mistake.
