Premiere Pro doesn't launch but states it's running in the task manager

[Reece5D34]

I have previously used Premiere Pro many times on this PC but it has recently stopping moving past the initial start up window; I have tried uninstalling and reinstalling, installing different versions, holding alt to wipe preferences and running as an administrator. Nothing moves it past the same point.

It gets stuck on "Loading MHPC_InitHelper.prm" every time.

This error occured before I tried updating it, I thought the update might do something different but it just did the same thing.

All other Adobe software work fine, only premiere doesn't, so I can't finalise projects like I normally would.

Any solutions? Reasons why not a single version works? Why did it previously work fine and why has it now randomly stopped?

Try clearing the plugin cache. You held down Alt to reset the prefs, now make sure all Pr processes are killed in Task Manager and launch Pr holding down Shift+Alt. The Shift modifier resets the plugin cache.

I've tried this but it's still stuck in the same place as before.

Do you have any third-party plugins for Pr or other Adobe apps? Plugins that *didn't* come with Pr?

For what it's worth, I had a very similar issue and it was resolved by right clicking the Premiere icon and launching it as an admin.

**This has worked** for me.. Premiere is now starting within 10 sec down from more than a minute.

Was facing the same issue where the screen was getting stuck at Loading MHPC_InitHelper.prm

Uninstall using the Adobe CC Cleaner: https://helpx.adobe.com/creative-cloud/kb/cc-cleaner-tool-installation-problems.html

uninstalling software and re-installing it is not a solution, that's crazy
