We need clear guidelines to solve 4.10 installation errors
I have the error code 1638 when I try to update my 4.10.0 to 4.10.1. (at first I got another error code but now its always 1638).
I already did read and try the many "solutions" suggested here & there but I'm still stuck with this error.
Windows 7 is fully up to date.
I tried uninstalling Visual C++ 2015 prior to installing 4.10.1 I tried starting epic launcher as administrator. I also tried a manual install of the pre-req prior to installing 4.10.1 I tried various combinations of all that.
Maybe I missed it somewhere but a clear guideline from Epic to better understand and solve those 4.10 installations issues would be very very much appreciated.
I found the solution, altho I still think we need some reference document to deal with the 4.10.x installation issues.
2 days ago I installed 4.11.0, without any problems.
1 day ago I tried to update my 4.10.0 to 4.10.1 : install failed with 1638 error code.
Here is the problem, as I just found out :
I uninstalled 4.11 pre-requisites files and the install process of 4.10.1 finally went fine. Now I'm wondering if I should re-install the 4.11 pre-requisites. Any input from Epic support on this matter would be really helpfull.
