Hello Tech Guys,

When I try to upgrade my system to latest version, I decided to install Adobe Flash and Adobe Reader. The download went pretty well and good but when I try to run or install it, I ended up with an error message. The error says that only a single instance of this application can run. Please help me resolve this error. Thanks in advance.

Hello,

It looks like your installer has got an issue. Download a fresh installer of Adobe Flash Player and then run the installer. Download Adobe Flash Player.

Also, try to close your browsers first and then run the installer. It is important because during the running process of browsers, the destination directory and other components might be busy so terminate them first.

Also, right-click on the installer and select “Run as administrator”.

For further troubleshooting, you can contact with this Adobe Help.

Hi Darline,

It means that you cannot run the updates in Adobe Flash and Adobe Reader at the same time. All you can do is to stop the process in Adobe Flash first to run the update in Adobe Reader. Right-click to the taskbar then select Task Manager. Sort all the processes according to description. Then select Flash Player. Right-click again and click to stop processes. Close the Task Manager then run the update in Adobe Reader.
