Been having this problem for days now, despite me updating all the drivers with Driver Easy and troubleshooting, everytime I try to update to 18.10.1 , it stops at partially installed as it states that there was an error message 1603, a general error. Looking at the installation report, only one thing failed:
AMD Radeon Settings
|Version of Item:||2018.1010.1801.32425|
I also see an error message at the bottom of the report that states that Package Manager could not find path.
