Tried to install darktable-5.5.0+755.g2fd7538c75-win64.exe.
Tried to start it with this:
“C:\Program Files\darktable\bin\darktable.exe” --configdir “C:\Users\Bill Martz\AppData\Local\darktable\” --library :memory:
and received this error message
you do not have write access to create one of the user directories:
C\Program Files\darktable"C:\users\Bill
please fix this and then run darktable again.
C:\Users\Bill Martz\AppData\Local\darktable\ already exists.
Any help?

You have had this before…I think its the space in your username… I should know the correction… normally you would use an underscore or something in your user name to avoid the issue with the space. Usually its not a good idea in Windows at least to have a space in your username or you will run in to this from time to time…
Maybe try this…
I tried:
“C:\Program Files\darktable\bin\darktable.exe” --configdir %LocalAppData%\darktable\ –library :memory:
and got the same error.
I thought the quote marks around “C:\Users\Bill Martz\AppData\Local\darktable\” took care of the problem. I have been using this for a couple years.

I think you still need quotes also around the path… and it may be a typo but should be --library not -library
I fixed it by moving config to a folder directly under C:
