Installing SoftDent on Windows 10 ERROR

I put an new SSD in my computer and installed WIn10.  Doing the install of Softdent keeps failing with an error about not having access to MSXML3.dll

The file c:\windows\system32\msxml3.dll could not be opened.  Please check to see if the disk is full and you ahve access to the destination directory.  Access is denied.

I am signed in with the domain admin login on a Windows active directory domain.

I was somehow able to get it installed properly on another pc in the same fashion. I though I just needed the .net redist installed. 

Any help is appreciated.

I am on version 16.1

Make sure you have full administrative read/write access to the drive.

Thanks I am signed in with the Domain Administrator account. That is admin role for the whole network. Any other ideas?

Well I was logged in with an account that was copied from the domain admin account, but not ADMINISTRATOR. I also ran sfc /scannnow prior to rerunning set up with the actual administrator account and this seems to have worked.

Re: Installing SoftDent on Windows 10 ERROR

Had the same issue on several new installations. Try the following from an elevated command prompt while logged in with an account having local administrative privileges:


takeown /F c:\windows\system32\msxml3.dll /A
takeown /F c:\windows\system32\msxml3r.dll /A
takeown /F c:\windows\syswow64\msxml3.dll /A
takeown /F c:\windows\syswow64\msxml3r.dll /A
cacls c:\windows\system32\msxml3.dll /e /g administrators:f
cacls c:\windows\system32\msxml3r.dll /e /g administrators:f
cacls c:\windows\syswow64\msxml3.dll /e /g administrators:f
cacls c:\windows\syswow64\msxml3r.dll /e /g administrators:f

This was provided to me by the installation team as a "fix", hope it helps!

Re: Installing SoftDent on Windows 10 ERROR

I did just end up running the install as the Domain Administrator account which solved the install problem.

Thanks for providing another option to the community.
