Cannot find DLL library file error

The error “Cannot find DLL library file” means that TradeStation cannot locate the MultiWalk DLLs in order to run MultiWalk.

Please review the following steps in order to resolve this issue.

Reinstall MultiWalk

Exit TradeStation completely and reinstall MultiWalk using the latest release.  The latest release can be downloaded here.

MultiWalk DLLs

Confirm that the two MultiWalk DLL’s (MultiWalk.DLL and MultiWalkStrategy.DLL) are in the TradeStation program folder. The default TS installation folder is C:\Program Files (x86)\TradeStation 10.0\Program. If you have installed TS in a different location, you will need to copy the two MultiWalk DLLs there.

The MultiWalk DLLs can be found in MultiWalk’s installation program folder.  This is the folder that you entered when running the MultiWalk installation program.  The default location is C:\MultiWalk\Program.

Install Microsoft Windows C++ Redistributable Libraries

The Microsoft Windows C++ libraries may be out-of-date or not installed.  Download the most current C++ libraries from Microsoft here:  https://aka.ms/vs/17/release/vc_redist.x86.exe.

Follow the prompts and install:

Running strategies on a different computer

There are some MultiWalk options that may require the MultiWalkStrategy.DLL to be present on the computer you are running the strategy.  You do not need to install MultiWalk on that computer, but the MultiWalkStrategy.DLL file will need to be copied to the TradeStation program folder.  See MultiWalk DLLs above on copying the DLL file to the TradeStation program folder.
