Error message: The windows installer service could not be accessed. This can occur if you are running in windows safe mode, or if the windows installer is not correctly installed. Contact your support personnel for assistance. I am not running in safe mode. I am on the administrator with full rights. This is a custom built PC. 7 months old. I have recently installed a 120 gig HD and that is why I am trying to install all of my programs on this drive. These programs/cds worked fine prior to the format and reinstall of the exact same Win 2k professional CD/os. These are my drive letters: A: floppy C: 120 gig [the new drive] D: DVD E: CDRW F: 60 gig G: 60 gig Due to making the 120 gig the master, I shifted my 2 old 60 gigs down to drive letters F and G as you can see above. I have tried to install from CD, MS Office, my MS Keyboard software, however other non MS softwares are installing fine, ie CuteFTP, MSWindows Media Player, WinRAR software. No problems with those. I have researched the MS site, and this one. I have even downloaded and tried to install the windows 2k windows installer 2.0 which is the latest version. But (and this is classic) I get the SAME installer error message to begin with! Someone please tell me something I have not tried?!? I have gone to MS website seen the Q229683. I have also tried the XP similar one (324516) I have tried the below fix: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSIServer 2. Double-click the ImagePath Value Name, a REG_EXPAND_SZ data type, and verify that the data string is %SystemRoot%\System32\msiexec.exe /V, where %SystemRoot% is the location of your OS, like C:\Winnt or C:\Windows. 3. Shutdown and restart in Safe mode by pressing F8 when the boot menu displays. 4. After you log on, run msiexec /regserver. 5. Shutdown and restart normally. It seems like I have been working on this forever. Please please HELP!!!!

It's been a long time ago, but I remember an article from MS that said this is a common form of "hardware conflict.” The solution is to upgrade the mainboards Bios, from the manufacturers website. It’s none of my business, but, wouldn’t it be a much faster unit if you put the Windows 2K programming onto a small(1gig) partition, and then use the rest of the drive for program storage, or whatever you’re doing.

Did you try this.. from the run command promt msiexec /unreg msiexec /regserver I saw that you tried msiexec /regserver... just do the unreg before you run the regserver.
