Adobe Reader 8.1.2 failure to install or uninstall

When Adobe Reader 8.1.2 is installed or uninstalled, the following error occurs: "the application cannot be changed ."Program. Check whether a valid Conversion Program path "or" No conversion program available "is specified"

Adobe Reader 8 doesn't know what's going on and suddenly cannot be used. When it is turned on, it says, "You cannot access the network location where the feature you want to use is located." The application conversion program cannot be installed, please confirm whether a valid Conversion Program path is specified ", delete it in add or delete software, and say" application transformation error, please verify whether the specified conversion path is valid ", it cannot be deleted because it already exists, cannot be opened, and cannot be reinstalled.

 

The possible cause is that other versions of Adobe Reader have been installed before and are not deleted. Some information is left in the registry, leading to re-installation failure.

 

Solution: modify registry information

Next, we need to modify or delete the information about Adobe Reader in the registry.

Open the Registry HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \ Installer \ Products

 

Find the folder whose productname is Adobe Reader and delete it, and then exit the Registry Editor.

 

The path for my version is 8.1.2 is as follows:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \ Installer \ products \ 68ab67ca7da72502b7448a200000030

One solution is to delete the path.

One solution is to find a transform in it and change it to null, prompting that the path in the information is the path

 

At last, reinstall the SDK or find the installation program 8.1.2 and then delete it. Everything works normally.
