Error when trying to run Macro (Can't open two workbooks with the same name at the same time)

[cmschmitz24]

Hello, I cannot figure out how to solve the error message that reads "can't open two workbooks with the same name at the same time". I create macros for my team of 8 people to use and they receive the same error message when trying to run a macro. When I create the macro they are saved in my addins folder but then I copy that macro into a shared folder. Downloading the macro does not cause any issues, it's only running it. Can someone help me with how to fix this? My team has been doing a work around by opening up Visual Basic and clicking the play button on the macro to run it.
