I neither know what a Pristine Install Stream is, nor does the message contain a hint about the path that is not found.

I've tried a `cleanup`, but the same error still occurs.

I [googled](https://www.google.de/search?q=%22Unable+to+create+pristine+install+stream%22&ie=utf-8&oe=utf-8&gws_rd=cr&ei=dXrkVqLqBYiU6ATygaTIDA#), but at the time of writing there are only 9 results available, some of them commit history of SVN changes, others unanswered question.

Answer: 
I dug into it with [Process Monitor](https://technet.microsoft.com/en-us/sysinternals/processmonitor.aspx) and I found a line (one column per line below)

```

```

Looking at my hard disk, I saw that there's no `tmp` folder inside my `.svn` folder.

Creating the `tmp` folder manually resolved the issue.
On my system, the tmp folder was in the .svn directory. So I did `rm -rf tmp` in the .svn directory. Then `mkdir tmp` in the .svn directory and it fixed the problem.
