Prior to the official release of the 2017 Autodesk products, I downloaded and installed the beta version of Civil 3D 2017 which of course included SSA 2017. The machine I had was running Windows 10. Civil 3D itself installed with no issues. SSA on the other hand did not. It kept producing an error message like the one shown below. I tried running the install as administrator, disabling anti-virus, etc. etc. Nothing worked.
At this point, I figured, ok. I will just go to the msi file for SSA and try to install using that. Well, the same error popped up. At that point I decided that since it was the beta, I wasn’t too worried about getting SSA installed. I also knew that the real 2017 products would be out really soon anyways. The thing that was bugging me was that I had a coworker who was also running Windows 10 that had no issues installing SSA 2017 from the beta! If someone else could install it on a Windows 10 machine, then the issue obviously was not with Windows 10!
When the 2017 products were released, I decided to give it another shot. I started with Civil 3D on it’s own, and the same thing happened. When the Infrastructure Design Suites were released, I decided to go that route. No dice, same issue. At this point, I decided to reach out to someone I knew at Autodesk to see if they knew anything about this. Soon after, I got a reply with a work around. The following is the unofficial fix that I was provided. One thing to note is that a new .msi file was provided to me so if you need this fix, feel free to contact me at: email@example.com so that I can send it to you.
Here are the steps to this work around:
1. If you have write access to the install files, replace the SSA Stand-Alone 2017 x86.msi with the new msi file (this is the file that I can send to you). It is located in the following directory (folders may vary slightly depending on operating systems)
For Suites: C:\Autodesk\IDSU_2017_Enu_Win_64bit_dlm\x86\Components\SSA
For Civil 3D: C:\Autodesk\Autodesk Civil 3D 2017\x86\Components\SSA.
As I said, these directories may vary a bit. A note from the developers is that the only difference with this file and the one that shipped is that this one ignores the return value of a regsvr32 call that is failing. This failure is why we were getting the error message.
2. Run the install again, and this time it should be successful.
3. Start a command prompt and Run as administrator as seen below for Windows 10.
cd “C:\Program Files (x86)\Autodesk\AWA\Support\RealDwg2017”
If all goes well, a message like the one shown below should appear.
