Opening a project in 158.2 that was saved in r159

I am having some minor frame rate issues with on of my projects. I wanted to go back to r158.2 which isn't the issue. But because I saved the project in r159, it is not letting me open it up in r158.2. Is there a way around this?

Careful! This is potentially dangerous.

The .caproj project file is essentially a (human readable) XML file. There is a version tag somewhere near the top, which you can edit.

If you saved as a single file (.capx) you have to extract that first, that can be done with any ZIP-program, it's just a ZIP-container with all the project files in it, including the .caproj

That does not always work though. If there was a breaking change to the file format between the versions, it will blow up and be corrupt.

Thank you for that information Eisenhans, I've always been very reluctant to upgrade mid project in case the new version broke something, knowing I can roll it back helps!! <img src="smileys/smiley32.gif" border="0" align="middle" />

You should not do this as a "regular" means of operation.

It's a "broken arrow" kind of thing, the possible consequences are ghastly <img src="smileys/smiley2.gif" border="0" align="middle" />
