I Had The Same Issue, I Fixed it by linking my paradox and steam Accounts then reverted to an earlier version of the game. This is from paradox itself and it worked 100% for me

Previously you were able to revert back to earlier versions of Paradox Development Studios (PDS) games at will on Steam. These specific versions predate the enactment of the General Data Protection Regulation (GDPR) - hence they are not compliant with the new policy.

In order to continue our endeavor to reach full GDPR compliance, we have designed a new system regarding the access to earlier versions of PDS titles: from the 1st of October 2018 onward all previous versions of PDS titles will be locked under a Steam password.

After 1st October, you will need to log into the Paradox Plaza website with your Paradox Account to access the codes for previous branches of each game that you own. This will, however, require you to link your Steam account to your Paradox Account. In an effort to comply with the GDPR, this is something we need to put behind the Paradox logins as it requires agreement to the Privacy Policy and Terms of Use to adhere to the GDPR guidelines.

To get the codes for previous versions:
Go to https://accounts.paradoxplaza.com/games and log in (or create) your Paradox Account.
You will have to link your Steam and Paradox accounts to see your games - where your codes will be listed.
To link your Steam and Paradox Accounts: simply go to the Settings tab. Under Steam account click connect (you will then be redirected to Steam to confirm your action).
With that done the Games tab on Paradox Plaza will show the list of codes needed to revert to previous versions.
See below to revert to older versions under passlock.

How to switch to old branch versions:
Go to your Steam Library and select your game of choice.
Right-click and select Properties.
Under the “BETAS” tab.
Enter the relevant code retrieved from Paradox Plaza and click “CHECK CODE”.
Select the version you wish to play and wait for Steam launcher to finalize the switch.
If the previous step fails, exit the game, right click properties, local files, Verify integrity of game files and wait for all files to be verified.

I repaired this by opening steam by administrator and starting hoi or just paradox luncher by steam

Changing the installer directory and running steam as admin worked for me

I have the same Issue. I have tried different installer directories, re-installing the game, running steam as an admin, tried to run the .msi file (launcher) through the cmd page as an admin as well, tried to start the game over the folder and nothing has worked so far. Does anyone know if there is a patch or something to fix it?

Go to C:\Program Files (x86)\Steam\steamapps\common\Hearts of Iron IV or another place were Hearts of Iron IV is installed. Search for dowser (.exe). Right click on the program and go to properties. Select the tab compatibility. Mark run this program as an administrator and apply. Start the game in steam and it should work. At least it did for me!
Or in this case Cities Skylines.

I went the other way, Run CMD as an Administrator, then run installer file thru it, the setup completes and the game just starts

This issue has been plaguing me for quite some time and this instantly resolved my problem, people should definitely try this before doing the much more convoluted roll back your game version option.
