If you find this error while installing leagacy system built on VB 6.0 then you just need to go to setup.lst find DllSelfRegisterEx and replace it with DllSelfRegister and offcourse save it and then run the installation wizard again.
Here is the process explained in steps
First you need to find a file name setup.lst in the package and deployment folder that you have created.
Then open the setup.lst file in notepad.
Replace all instances of DllSelfRegisterEx with DllSelfRegister
Save the setup.lst
Run the installation wizard again.
Hope that helps
Code is poetry

Mine was a bit different on a win7 64-bit architecture. But all I did was remove TmpDir=msftqws.pdw and it got past the error and worked. This helped me in the right direction. Thank you very much!
