I have seen lots of issues about the game not working after reinstalling or patching. I have had the issue myself at times. And one thing I have had to do just about every time is reinstall the game entirely AND add old dependency components that windows no longer comes with.
Microsoft .Net 1.1 - https://www.microsoft.com/en-us/down...ils.aspx?id=26
Microsoft C++ Runtime 2005 - This one will be difficult. There are many versions and the one you need is actually so old, that you will have a hard time finding them. The MS provided one https://www.microsoft.com/en-us/down...ang=en&id=3387 is the latest/last one they did before the next major version. However it does not contain everything ddo could need. So here are additional ones:
https://www.microsoft.com/en-us/down....aspx?id=26347

https://answers.microsoft.com/en-us/...6122af4?auth=1 has links from a rep for additional redistributables, but none are for VS C++ 2005. However it does have info on registering components if that is the block.

https://support.microsoft.com/en-us/...al-c-downloads talks about the latest MS supported ones and explains what they are a bit.

However, and this site is not an official MS site, what you ultimately want is from http://www.oldversion.com/windows/directx/, The 9.0c's from 2005. You could get all the DX9's and it should help more than harm. A big warning though: THIS SITE IS VERY AD HEAVY! BE READY TO BLOCK ELEMENTS, ADS, AND CLICK THE RIGHT BUTTONS TO GET YOUR FILE. I would highly recommend finding a more professional source for the proper file, however I have yet to see the right files on the forums, or online as a whole.

If the devs have a legitimate source for the files, sharing that would be preferred.
