I'm portable-addicted and I use others apps on my USB-stick - skype, PSI, Total Commander, Private Data and many more. Sometimes i had problems with run them from it - it was many .exe files in directory, application must have som params or environment variables set berore it is run.
So I developed a small application that runs other application (that supposed to be a portable one) from (for example) App directory.
I can configure all application parameters and define Environment vars before run.
I found it very helpfull, so - If You thing it's interesting - try it.
It could be found
I'm waiting for Your opinions, and woul'd be gratefull for Your english corrections.
Have a fun.
