By default, the ElectricFlow agent runs the cmd shells found in System32 directory which on 64-bit systems is a 64-bit cmd shell.
It you want to debug the setup of 32-bit applications, such as a ElectricFlow agent or encryption software, which may work different in 32-bit than 64-bit mode, you must use the 32-bit command line environment.
- Use msinfo32.exe from a command shell to determine the OS architecture. Under the "System Summary" the field "System Type" will say 64 or 32.
- Make sure the WOW64 package is installed on your 64-bit system.
- When you open a cmd shell, it will be a 64-bit cmd shell.
- Reference a direct path to the 32-bit WOW64 command shell in the step "shell" entry.
By default, most Windows systems use this hard coded path:
Because the cmd inherits the parents environment (the agent is running 32 bit remember) the following will detect if you are on a 64-bit system.
IF PROCESSOR_ARCHITECTURE == amd64 OR
PROCESSOR_ARCHITEW6432 == amd64 THEN
// OS is 64bit
// OS is 32bit
