If you’re encountering an error message similar to the one below, this solution is relevant to your situation:
System.ComponentModel.Win32Exception: An error occurred trying to start process ‘C:\Users\xxxx\AppData\Local\Bloxstrap\Versions\version-24872f7beace4d0a\RobloxPlayerBeta.exe’ with working directory ‘xxxx’. Access is denied.
Recently, antivirus programs, particularly Avast, have begun mistakenly flagging Bloxstrap’s download of Roblox as potentially harmful without clear reasons. This leads to Avast blocking Bloxstrap from launching Roblox.
To resolve this issue, add Bloxstrap’s installation folder as an exception in your antivirus settings. If you’re unsure how to do this, search online for instructions tailored to your specific antivirus program.
