Please be a bit more specific:

• Service Pack?
• RAM?
• Installed via what app?

I did check for that on the WB website, but it didn't tell me that. I had feeling it had something to do with the update  

From Neil Banfield, WB Dev., on WB 6.3 Support thread.

Actually if you read that you will see it says Vista 32 or 64 bit.  Not XP.  When we added the ability to run on 64 bit XP in 6.1 we were clear that it was unsupported.

We are looking into making the installer install 6.2 on XP 64 bit instead of the 6.3 files.

You might be right, but it is just not clear and as such just not fair to the potential customer. I lost count on how many times I had to write emails to Software-developers and ask them "If you say 'Vista', do you mean both 32bit and 64bit?" (The habit of not clearly defining the OS required was especially frequent during the first year after the Vista release, and has improved since then). Some answered with "yes we mean both" other said "we mean only 32bit".

I can easly see how one would think that 'XP' means both versions, especially when the software in question also supports the 64bit version of Vista.

I would suggest to change the description of WB to make it clear that the newer versions only support 32bit XP.

This might be changed to:

As to further clairify XP 64bit's exclusion from the current supported OS's.

But yes I did read it as it was intended, with a non inclusion of the 32/64 bit terms like Vista has, I understood it as only the standard XP (32bit) was supported.

As I have said elsewhere, the plan is to upate the 6.3 installer to install 6.2 on 64 bit XP.  Until this happens you can contact support who should be able to provide you with 6.2 and you should have all your existing features back.

Being able to run on 64 bit XP was something that was added based on user feedback last year.  At the time it was made clear that we would not provide support for this and it was the end of the line for 64 bit XP and the trial of WB will not install on 64 bit XP.

This particular issue happened because we no longer test on XP 64 bit as it is not a supported platform.  Part of the reason for the removal of support for 64 bit XP is due to the increased testing it requires which has been well in excess of the benefits we get from supporting this platform for a very long time. 

As for the blurb in SDC, I suspect someone got carried away and copied the text from WB 5.5 (which did support those OSes) and didn't notice their error.  I have passed it onto the right people so they can correct it.

I should also point out that XP means XP 32 bit when it is listed in our system requirements.  XP 64 bit edition is a seperate OS and unless it is specifically mentioned in the system requirements section there is a good chance our apps will not run on it.
