error description

Help the customer install ArcGIS, report Error: Error 1935: An error occurred during the installation of assembly, then check the information and say to uninstall the .net framework, and found that there is a problem with the installation of the .net framework. When uninstalling the 4.8 version of the .net framework, get error: can not access Windows Installer service.

Here I record the process of reinstalling net framework.

solution

I read many many posts and tried many times according to the steps. I don’t know why the .net framework can’t be uninstalled.

1 check whether your own system is 32-bit or 64-bit (check the properties of my computer right-click)

2 Run cmd as administrator

//32 is the system
cd C:\Windows\System32
msiexec.exe /unreg
msiexec.exe /regserver
//64-bit system
cd C:\Windows\SysWOW64
msiexec.exe /unreg
msiexec.exe /regserver
//Register dll (64-bit system as an example, if it is a 32-bit system, enter the C:\Windows\System32 directory to execute the registration command)
cd C:\Windows\SysWOW64
regsvr32 msi.dll

3 Windows+R open the run window, enter services.msc to open the service management window

4 Find Windows Installer, set it to start manually or automatically, click Start

5 Open the cmd window and run the sfc /scannow command

6 Restart the machine

7 Download a Windows Installer removal tool, find .net framework4.8, and click Delete.

8 Open the uninstallation and installation program, find that the .net framework4.8 is still there, click to repair after a while, after re-downloading and installing, there is no prompt to access the Windows Installer service

9 Reinstall the arcgis software, everything is normal
