Error: malformed string on input

I created a project and transferred the project fold to a different computer which I have done before and nothing happen but today AutoCAD Electrical is giving me an error. It says error malformed string on input and it doesn't let me draw any wires or do anything autocad electrical related. I can draw a normal line fine but can't draw a wire or insert a symbol. Just wondering what that error means and how to fix it. Also I have done autocad electrical drawings on this computer before in a trial version and we just got the licenses for it and installed it and now its not working for some reason.

I had your exact issue plus some others and here is an answer i found to work for me.


Did you try to delete the lastproj.fil in your roaming support user folder if you using Win7?


Maybe it got corrupted due to random crash or error in ACE.


Windows XP: \Documents and Settings\{username}\Application Data\Autodesk\AutoCAD Electrical {version}\{release}\{country code}\Support\User\

Windows 7: \Users\{username}\AppData\Roaming\Autodesk\AutoCAD Electrical {version}\{release}\{country code}\Support\User\

hope this helps
