I downloaded TTU 14.10 for Windows from TD Dev Exchange. After unpacking the zip file, I looked for setup.exe as directed by the web page. There are multiple versions of that executable in each of the sub-folders for the tools, but no setup.exe in the TTUExpress folder. However, there are 3 executables, TTU_Base.exe, TTU_DBM.exe, and TTUListProducts.exe. I guessed and ran TTU_Base.exe. After starting, it appeared that this was the actual install executable. I selected all the products and ran the install. I then ran TTU_DBM.exe, again selecting all products and ran the install. It appeared that the install completed successfully.
However, the install removed all the entries from my Windows Path environment variable and left a single entry pointing to one of the TD utility folders. None of my programs would run from any icons either on the task bar or start menu. I was able to open a command prompt and eventually restore the basic Windows search folders to the Path variable. I was able to start the Windows restore and, fortunately, had a restore point.
In addition, a large number of Windows icons reverted to the generic Windows icon. The restore did not fix that problem.
I left out the environment:
Win 7 Pro 64 bit, 16GB memory, 1TB disk, I-73520M @2.90GHz. More than enough resources to complete the install
I am having exactly the same problem. I suspect that it is caused by Teradata Studio. It seems to occur primarily when I've been using that program. Although it is very inconsistent. I cannot force it to happen. The only fix is to log out of windows then back in.
