I am a Presonus Studio one 4 user.
I was able to use this software without any problem up to version 3 and version 3.5.
The following problems have occurred since version 4 and version 4.5 where "Plug-in Scanner" was introduced.
The plug-in scanner is displayed as "●● (the plug-in name) failed to scan" when starting up the DAW, and it is not possible to load all third-party plug-ins other than the Presonus-provided plug-ins.
The symptoms are as the attached image.
All 531 plugins fail to load.
To solve this problem, I did all the following:
■ Uninstall and reinstall Studio onen using various software such as "Revo Uninstaller"
■ Resetting and rescanning of blacklist by Studio One
■ Check if the installation location of the plug-in is appropriate (all of them are placed in the correct directory of Windows, and Studio One side exists in the default location where the plug-in is loaded)
■ Security software off and operation permission of each software by security software
■ All execution authority is given to each software
I am not a PC or DAW beginner.
At work, I sometimes advise people about music software related errors and even help them solve them.
I tried everything I could come up with to solve the problem.
In Studio 3.5 you can load plugins as before.
The addition is successful even after installing the new plug-in.
Because of this, I have failed to uninstall Studio One 4 completely, and I expect that some files related to Studio One 4 remaining after repeated uninstallation cause this error. You
Please tell me how to uninstall Studio One 4 completely.
I think that there are log files and registries that can not be completely removed by normal uninstallation or uninstallation using uninstall software.
I want to know where the file exists.
When I succeeded to completely uninstall Studio One 4, I think that I can finally install this software in a completely clean environment, and the plug-in loading is likely to be normalized.
I became a Studio One user from a SONAR user and had a very comfortable experience.
That is why I feel serious about the problems that are occurring now, and I would like to solve them anyway.
