Software Deployment

When I launch certain applications I have just started getting an AppV error: . . . . 'There is not enough space in the appv cache. 0000E029 'This may seem a little obvious however I have unloaded all appv apps, I have cleared the global cache and even deleted the local PKG files. When running a WMI query I have 100% free space (6GB which is much greater than my 500mb app). In registry under the HKLM hive I have set the AppFS to clear apps persistently but I am still getting the error. When searching on the web I see the same suggestions: Increase the cache size, clear the cache but this is not the case here. I'm hoping I've missed something obvious and someone can offer something beyond the two previous suggestions. .The environment is config manager 2012 delivering the MSI and APPV 4.6 running in standalone. (OS is win 7 x86).Thanks.
