Wait, so I have mixed thoughts here, I am going to install DirectX 9 manually which means it should fix that error as itman said however, if not I will try what peteyt said and do a repair by keeping all the files. Thank you guys I will keep u updated.

So I have tried a few versions and 10.1.245 works great it did give me the option to update but I am gonna hold back for a few days and see how things go, thank you so much.

Hi thanks for the suggestion, do you think I should revert back any updates or install this missing .dll file? Any registry editor errors?

Hi,

I want to purchase ESET NOD32 premium but I want to get a trial before I actually buy it. However, I am having problems with installation. It installs properly, however it does not run when I click on the icon it opens a pop-up and says d3dx9.dll is missing or corrupted? So, I tried to uninstall it manually and it still gave me the same error, I am running Windows 10 1903 with the latest updates and all the drivers properly installed. I tried downloading it from this link : https://www.eset.com/uk/download/ I wanted the home version with 30-day trial as my old one runs out in about 4 days so decided to change vendors. The program still keeps giving me the same error so I decided to give other sources a try I tried downloading it from https://securedyou.com/download-eset-nod32-antivirus-2019-free-full-version/, so for some reason it works but there is no pop-up or button to activate a trial?

Thanks
