If you receive a error message similar to "Rainmeter.dll (32-bit) error 126" or "Rainmeter.dll (64-bit) error 193" when launching Rainmeter, it usually means your system is missing libraries required to run Rainmeter.
The Visual C++ libraries are missing from your computer.
To fix this issue, download and install the Visual C++ redistributable packages. Download the correct version (32-bit or 64-bit) depending on the error message.
Your computer has corrupted or invalid copies of the Visual C++ libraries.
To fix this issue you may either:
Once the download is complete, extract the downloaded .ZIP archive and copy the contents (e.g.
atl110.dll) to the Rainmeter installation directory. You should be able to launch Rainmeter now.
