--- Comment #3 from Vamp898 vamp898@ignaz.org --- There are news on this.
I was able to run this software perfectly fine in CrossOver Linux.
First i created a new Bottle (32bit) and tried to install the Software --> then i noticed that CrossOver doesn't use Wine Mono which caused the Setup to recommend me to install .NET 4.0 but the installation stuck at downloading .NET
Then i did the following
manually download .NET 4.0 from microsoft.com --> giving it to the Bottle in CrossOver --> It detected that i want to install .NET 4.0 and also installed other Version of .NET like 2.0 and 3.5 when i remember correctly.
After that i was able to install SPP in that Bottle and it runs fine. I can open and develop RAW files without any issues.
I tried to reproduce this in wine but after installing .NET 4.0, when i try to install SPP wine keeps telling me that i need wine-mono but then SPP fails with the same error as before.
When i install wine-mono first, .NET complains about .NET is already installed.
So in CrossOver it works right now, the question is what have to be done in wine to make it working.
I personally dont care as i have a working solution and i also like to support the wine project by buying CrossOver but still, others might not find this solution suitable.
