How to uninstall the new version of adobe flash player activx and install the old version for testing.

When we develop software, we often need to simulate the user's computer environment on our own computer, such as a virtual machine. If the flash version of 10.0 in our user's computer is 11.0
In this case, we need to uninstall the old 11.0 flash player and install the old 10.0 flash player version.
 
The installation fails when 10.0 is installed today. It is said that my flash version is not the latest and cannot be installed. To download the latest version, the new version cannot be retried due to network disconnection.
It should be a registry issue. Baidu search and find the following solution.
 
In the 360 Forum, find a key: (we only need to find a registry key to delete the key value of the version higher than the version to be installed .)
 
 
Open the Registry (START-> Run-> regedit) and find the following location:
 
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Macromedia \ FlashPlayer \ SafeVersions]
 
"6.0" = dword: 00000058
 
"7.0" = dword: 00000046
 
"8.0" = dword: 00000023
 
"9.0" = dword: 002f0000
 
Delete "9.0" and "10.0", and then click the installer installed and downloaded to see the effect. I hope it will help you.
