User blog:Sliixey/How to fix install problem on Roblox?

How to fix this problem? The text says the system cannot find the file specified. Here's a picture:

If you know how to fix this then please tell me. It's been displaying this message for a few days now. Here's some context. I was on this simulator and you had to click to get skill. And I got tired of clicking it so I downloaded an autoclicker on SourceForge and my anti virus: Bitdefender thought it had a virus. So I went on Bitdefender and restored the application because I knew it did not have a virus and it worked. Then I ran Roblox (with the autoclicker) and Bitdefender detected another malicious behaviour and I got the notification and it put RobloxPlayerBeta.exe on quarantine and I tried to run Roblox but it wouldn't work, so I uninstalled and reinstalled Roblox hoping it would work but it just made things worse and now it displays this message.

- I resetted my pc and it still didn't work.

- I tried to uninstall roblox properly on the control panel and it still displays the msg.

- I tried watching videos but none of the ones I watched show this exact problem and how to fix it.
