The typical App-V error code consists of 2 x 4 bytes in the form hexadecimal: "0x000000-0x000000". The first six characters refer to the App-V source code and can be ignored. For error analysis the last 10 characters are interesting. So "00-0x000000". The first two characters show the type of error and the source. The last eight characters are the actual error code. Once an error code is returned as a decimal number, then this decimal number must be converted to a hexadecimal value for analysis.
