FAQ #26352, published on 2024-12-13
What should I do when WINDEV SaaS launches with the error “48: HPVlib token installation error or haspvlib missing”?
This feedback appears if a driver required to run WINDEV could not be fully installed. It is most likely blocked by a security device. 

I advise you to do the following:
- temporarily stop any security programs such as antivirus,
- download and run the haspdinstpcs.exe utility https://package.windev.com/pack/addons/hasp/haspdinstPCS.exe
- authorize elevation of privileges,
- click on “Install drivers”,
- restart the computer once the “Operation successfully completed” message has been validated.

Once these steps have been completed, WINDEV should launch without difficulty. Don't forget to reactivate your security devices.
