Retopoflow cant activate without administrator privileges

Thanks for the report, @buzzrapide.

Unfortunately, we've seen that some versions of Blender (especially for Windows) do not include some of the Python libraries that we use, but some versions do.

Are you using Blender 2.79b? Where did you get the installer? Did you use the installer or download the zip?

[buzzrapide]

Its on blender 2.79b and both installer and zip doesnt work and i got them on the blender website

[EmeraldEelEntertainment]

I have the same issue too. I'm using 2.79.

Ok, this is somewhat of a known issue. see https://docs.blender.org/manual/en/dev/troubleshooting/python.html#mixed-python-libraries-dll-s

A question for you all: What other Blender add-ons have you installed or enabled?

Here is a possible workaround:

1. exit Blender (in case it is open)
2. rename the 2.79 folder in C:\Users\YourName\AppData\Roaming\Blender Foundation\Blender\ to 2.79.bak or something similar.
3. start Blender
4. install RF

Note: any add-ons installed or settings stored in the 2.79 folder will need to be reinstalled / re-set. If all else fails, you can simply rename the 2.79.bak folder back to 2.79.

I noticed you have to Run Blender in Administrator mode for Retopoflow to work and or Activate

@vxlcoder do you have a windows machine at hand to look into the Administrator mode requirement? That shouldn't be the case.

[vxlcoder]

Interesting. I have never had this be an issue before. Maybe Blender was installed by an admin, and the settings are stored in a folder that needs special permissions to write into? @Reoxur, what happens if you download Blender as a zip file, extract the folder to a personal folder (ex: C:\Users\yourusername\Downloads), install RF, and then try to activate it?

Hmm, I also wonder if socket.py tries to open a port (or something like that), and the Windows permissions prevent it for some reason. I'll look into that more.

[Reoxur]

I guess I do have a messed up Windows install I mean I am the admin but things still require admin to run sometimes

And your right, if I installed Blender in a personal folder it doesn't require admin. And Blender right now is installed in "Program Files" folder where it does require admin but only for Retopoflow it seems.

Its not really an issue but I can imagine some people wouldn't know they had to run it with Admin.

Thanks for the feedback, @Reoxur!

Could you do something for me? Can you start Blender (the Program Files one) from the terminal (or open the terminal after starting), try to enable RF (which should fail), and then copy-paste everything that was reported in the terminal? Thanks!

This is what shows in the terminal

[prophet067]

Hello, I am having this issue currently in Windows was there ever any fix found?

[Reoxur]

@prophet067 Try run Blender as administrator

[prophet067]

Hey @Reoxur I tried this but still the same error

[James-mwangi]

RF does not activate even after i try the suggested fixes above

[vxlcoder]

@ArtBlend and @James-mwangi, you two are seeing a different problem. Your problem should now be fixed in commit 87ae7fd. Try pulling the latest version of release/2.0.1 branch. Let us know if you still have problems.

@prophet067, try downloading and unzipping Blender to your desktop (rather than installing it). Then, run the Blender.exe that is inside the Blender folder on your desktop. Your issue may also be a permissions issue.
