SCFLicense: Extension Licensing on Sketchucation
-
This is normal since licenses are attached to computers. Did you follow the instructions?

Hello,
I’ve been a customer of yours for years and already own several plugin licenses. Recently, however, I’ve been experiencing an issue with the JointPushPull extension. My license seems to have a problem—whenever I try to use or manage it, I receive the following error message:ERROR_A04
Wrong Signature File – You may have changed the computer name
It is advised to erase the Signature file and revalidate.I’m not sure how to fix this. Could you please help me resolve it?
-
Click OK in the popup alert. This will open the location of the signature file.
Delete the file named SCFLicenseSignature - DO NOT MODIFY OR DELETE.txt
Restart SketchUp
Activate license

Hello,
I have a FredoScale license with 3 activations. Currently, only 2 are in use, but I need to release one activation or reset my license. Can you please help me reset or release a license slot? My SketchUcation username is: Igor , and my license code is: [REDACTED].
Thank you! -
Hello,
I have purchased a Perpetual License for FredoScale, but I am now receiving a message that I have reached the activation limit (“number of created reached” or similar) and I can no longer activate the plugin on my computer.
I have used the license on several devices and/or reinstalled my system a few times, which may have caused this issue.
Could you please help me reset or extend the activations for my license?

hello, can you help me? I have 4 fredo licenses, but non of with it's working.
After a recent Windows update, I’m getting the ERROR_A04 ("Wrong Signature File") when trying to validate my license. I already deleted the signature files, updated the extensions, and ran SketchUp as administrator, but the issue persists. -

hello . I have a license. But I can't activate it. I get this message. What is the reason?

-
Very likely you are trying to validate the license of FredoCorner with a license of RoundCorner, or the reverse.
