Hi, the task folder should not be saved to the installation folder by default. 
The installation folder is located at C disk, and you may have no access to C 
disk when running in normal user mode.

You don't have to re-install pLink currently, although installing pLink to C 
disk can also cause some error in some computer.

Please first try to move the data file and database file to another folder, 
and also create a new task in another folder. The `Desktop`, `Documents`, or 
`Downloads` of your account is recommended, because in most cases you have 
full access to these folders.

If similar error still occurs, you can also try to re-install pLink to another 
disk. The license file can be reused, and no extra application requried.
