Rainmeter.dll Load Error 126 -

Error 126 is, statistically, a Visual C++ failure. Rainmeter 4.5+ requires the Visual C++ 2015-2022 Redistributable (x64 and x86). Even on a 64-bit system, you need the x86 (32-bit) version because Rainmeter’s core still has 32-bit dependencies.
If your Rainmeter installation itself is corrupted (not just the DLL dependencies), a clean reinstall is necessary. Do not worry – you can save your layouts.
At this point, we’re dealing with a corrupted user profile or a deep Windows permission issue. Create a new Windows user account (local admin), log into it, and try installing Rainmeter there. If it works, your original profile has a corrupted registry or permission lock—migrate your skins and settings, then retire the old profile.
