Toolbox App: Installation fails: Access to the path was denied

Question

The JetBrains Toolbox App installer reports an access-denied error. The message points to a file under C:\Users\<username>\AppData\Local\JetBrains\Toolbox\bin.tmp, for example:

Access to the path "C:\Users\<username>\AppData\Local\JetBrains\Toolbox\bin.tmp\7z.exe" was denied.

How to resolve this problem?

Cause

The installer cannot write to or execute files in its temporary extraction directory. Common causes:

• some other app use this directory at the same time;
• antivirus or endpoint-security software blocking execution, or by restricted permissions on the target directory.

Answer

1. Download and run the latest installer from the JetBrains Toolbox App page. Recent versions report this condition more clearly and offer a retry option.
2. Run the installer again — the error is often resolved after a second try if the reason was that another app temporarily holds the directory.
3. Try running the installer as Administrator.
4. If the error persists, check your antivirus and other security software to see if it blocks the installation. Add an exception for the installer or temporarily disable it during installation.

Note: In corporate environments, steps 3 and 4 may require your system administrator’s attention.
