Re: WDSCI-L Digest, Vol 7, Issue 262

I've installed and used Rational Application Developer on Windows Vista Home Premium 64-bit and used it for a lot of Rational Business Developer/EGL things. Not sure if it's officially supported by IBM or not - it should be - industry is selling a ton of 64-bit PC's now. It works very well.

Only hitch I remember was I needed to install it within the 32-bit directory structure ...\Program Files (x86) or I had an install failure towards the end of the install process. The default install directory path is ...\Program Files (x86). I just ran into problems trying to change it to outside that structure. Also, it might help if you right-click on the install executable and say "Run As Administrator" even if your account is an administrator account. This last thing is more of a Vista thing than 64-bit.

RDI or RAD will be a 32-bit application running on 64-bit OS, just like Microsoft Office or Quicken, etc.

I don't see any reference to 64 bit OS's on the RDi 7.5 CD documentation. Every reference specifically points to 32 bit for Windows and JRE.

Always hard to surmise from one OS version to another. RDi runs fine on W7 (32bit). I would be surprised if 64 bit was supported for WDSc but not for RDi. The other way around maybe (in this case NOT) but usually each version adds better OS support rather than curtailing it.

If I had a 64 bit machine I might try installing 64 bit W7 and see what happened. However, my only 64 bit machines around here are Power, not Intel.


I don't know the status of RDi (we haven't gotten there yet). But if I recall correctly, Eclipse doesn't (or at least didn't) support 64-bit Windows. Hence WDSC couldn't support it either. I seem to recall a post by Joe Pluta a year or two ago on it.
