I just upgraded CCS from 2.21 to 3.1 on a PC that runs Windows XP Professional with SP2. I must use this system with standard user privileges. Installation worked without any problems under administrator privileges and registry entries 'HKEY_LOCAL_MACHINE\Software\GODSP' and 'HKEY_LOCAL_MACHINE\Software\Texas Instruments' were set to full control for my user account.
When I run CCS as standard user, I encounter no problems as long as I work with projects that do not use DSP/BIOS. However, If I try loading a DSP/BIOS project, I get a dialog titled 'Project Update' with the message 'CRegistryInfo::GetSABiosRegKey() could not find BIOS registry entries'. If I then select any of the DSP/BIOS analysis windows, like 'CPU Load Graph', I get an error dialog with the text 'Unknown error. A required library is not loaded: vbd.dll'. I do not encounter any of this problems if I log into my PC as an administrator. A TI Knowledge Base search did not reveal anything that would address my problem.
Any help will be greatly appreciated.
