i run into problems working with DIAdem 9.1 on Windows 2000 SP4!
The Diadem installation went quite well.
My problem:
only "Administrator" and "Power User" have the privilige to "WRITE" to the DIAdem install directory.
Trying to start Diadem as non priviliged USER I get something like:
DIAdem Configuration-Drive "C:\PROGRAM FILES\ NATIONAL INSTRUMENT\DIADEM 9.10" WRITE PROTECTED!
I installed & started DIAdem for one
time with Administrator rights. I activated the Product and exported
the KEY to a License Server. Everything works fine for Power Users an
Administrators. Only "simple" USERs are not able to start Diadem due to
missing WRITE permissions.  i can't grand this permissions to
normal USERs :-(
Playing around in Registry -> "RegWriteAccessAllow" ("0","1") (DWORD) (HKEY_LOCAL_MACHINE/Software/National Instruments/Diadem/9.10),
didn't solved the problem.
I switched back to "local License" Managment (local Key files) but the Probelm persists.
thanks in advance
P.S.

Hi DirkT,
Running DIAdem with User rights has different aspects we need to look at.
1) Registry Write Access
Launching DIAdem the first time with administrative rights registers some OLE components in the registry. After this step no more Admin rights are necessary for the registry. However running DIAdem as user might result in error messages as DIAdem tries to re-register the components again. You can avoid this by setting the RegWriteAccessAllow Key to 0 (see online help under "Administrator Notes")
2) File / Folder Write Access to the DIAdem Installation Folder
DIAdem needs write access to certain files e.g. the error logfile DEM_ERRS.001 or DESKTOP.DDD when saving configurations. You may change the folder where these file are being stored and searched for to a writeable folder by launching DIAdem with the "/d<NewFolder\MyDesktop.ddd>" start parameter or by setting the environment variable "DemDDD" to that folder. Then move the following files from the DIAdem installation folder to your new writeable folder:
*.ddd
userpar.par
dem_errs.*
3) File / Folder Write Access to other Folders
There are a number of other folders that DIAdem 9.x needs write access to and which cannot be changed. All of these folders are located by default under "%ProgramFiles%\National Instruments\Shared". Currently you need your Admin to give you write access to that folder and below
For future versions of DIAdem the team is working to make running under user rights easier.
Hope that helps,
Marcus
