Installed 8.5 and now I can't build an installer with 8.0

[mike72903]

I've been using 8.0 to write some applications.  We have the professional development system contract or whatever with NI providing upgrades.  Our IT dept came and installed 8.5 on my computer.  I used it for a short while, then went back to 8.0.  I have not un-installed 8.5.   I'm now experencing problems building an installer with 8.0.  I get the message box that it is "unable to locate the installer source for NI Labview 8.5 distribution" and a default D drive for the original CDs which I don't have.  I do have the original 8.0 CD's and mainly for that reason  want to continue to use 8.0.  In the build process I am using additional installers for datasocket and visa 4.2.  If I uncheck them the install process will complete.  Is there someway for me to force my installer builder to use the 8.0 files instead of 8.5?  Could I do this by un-installing 8.5?  I re-installed 8.0 hoping that would help but it did not.  I searched for this problem and found several earlier postings concerning this problem but none specific to this particular issue.  thanks for any advice, Mike

Mike,

Application Builder is looking for a CD/DVD and or copy with the same ID # as the disk used for install.  This ID # is stored in the widows registry and can be difficult to remove during a normal uninstall.   Reloading 8.0 after 8.5 is installed is probably not going to work because the 8.0 install will not replace newer versions of  NI-VISA.  One way that I know will work is to uninstall 8.5 using msiblast.exe and then reinstall 8.0. 

I've attached a copy of msiblast and the last set of instructions I received from NI when fighting a similar problem.

Thanks for the input centerbolt.  What a pain huh?  I'll have to think about if I want to do all that for a while   While I have administrative rights on my pc, the IS dept. is so paranoid what people might do I'm uncertain of restrictions that might stop me part way through and then be unable to recover or something.    I like LV a lot but not real happy with the build processes for compiling programs and installs.  If I copy the  LV CDs to my C drive and then do the installation from there rather than the CD drive, will the program installer quick defaulting to the D drive for unfound drivers?  Does that make sense?  Anyway, thanks again.

Mike,

Yes it can be very painfull at times.  The main problem is really with the NI installers and uninstallers.

Copying the distribution CDs to your harddrive or to a network drive should work.  Probably a must have if you don't have direct control of distribution cd's. 

 I've recently started doing that just so I don't have to keep rummaging about for the stack of cds.
