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.

Well, it seems that the red dominance problem is also present in 
version 2.3. Actually, the change with target color temperature 
appeared in this version: "Target White Point for LCD is now 6500K 
instead of Native.". This can of course explain why the red dominance 
appeared. If the target white point is set at a higher temperature, 
there's a shift toward low temperatures. So I ask: why this change? 
To encourage us to purchase the pro version?

As a matter of fact, I currently can obtain a correct calibration 
only with version 2.2.

Also, this is in contradiction with what the support said about 
version 2.3.5. I obtained the very same result (red dominance) with 
the new version and the new device driver as with version 2.3. So 
this version "works" on a 32-bit system.

I can only repeat this again and again: what a mess! What a loss of 
time!

Yes. Excerpt from their answer:

"
Hi Patrick,
As mentioned on the site this version is only for 64bit systems and you 
should not install it on a 32bit system.

So now you have to deinstall again the complete installation and 
install the version 2.2.
"

So please, get things in sync and consistent. The information on your 
web site actually states that version 2.3.5 is 64-bit only. I could 
finally make clear that it is not the case.
