Short paths

In case the error still appears, it means that there is an issue with short paths.

To resolve it, please follow these steps:

  1. Close all MultiCharts products and make sure all MultiCharts Processes are finished in Windows Task Manager.
  2. Go to the Windows Start menu and type Regedit. Launch the Registry Editor.
  3. In the Registry open the path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
  4. Change the value of the NtfsDisable8dot3NameCreation key to 0.
  5. Reboot the operation system.

After the system is rebooted,

  1. Launch MultiCharts: right-click the shortcut -> Run as administrator (if you don't have this option, use regular double-click).
  2. In MultiCharts go to File -> Preferences.
  3. In the Misc tab change the Studies directory: click the ... button for Studies (remember the old path). It is important to use a simple path. We recommend creating C:\MyStudies.
    Note: The Permissions for this new folder should be set to Full Control for all users that will access this folder in the PowerLanguage Editor.
  4. Close MultiCharts.
  5. Make sure all MultiCharts Processes are ended in the Windows Task Manager.
  6. Copy the whole Studies folder from the old location (for MC 32 bit: %allusersprofile%\TS Support\MultiCharts\StudyServer; for MC 64 bit: %allusersprofile%\TS Support\MultiCharts\StudyServer) to the new one (replacing the existing files).
  7. Restart MultiCharts.

If your MultiCharts version is below 8.8 and you are unable to update please follow these instructions:

  1. Open the compiler_error.log file. Depending on what path is written in the file you will have to rename several folders in one of 2 possible locations:
  • C:\ProgramData\TS Support\... (example for Windows 7/8); C:\Documents and Settings\All Users\Application Data\TS Support\... (example for Windows XP)
  • C:\Program Files\TS Support\... or C:\Program Files (x86)\TS Support\... depending on your Windows and MultiCharts version.
  1. Rename the TS Support folder into TS SupportOld. Create new folder TS Support. Move everything from TS SupportOld into the new TS Support. Delete the TS SupportOld folder.
  2. Open the new TS Support folder. Rename the MultiCharts folder into MultiChartsOld. Create new folder MultiCharts. Move everything from MultiChartsOld into the new MultiCharts. Delete the MultiChartsOld folder.
  3. Open the new MultiCharts folder. Rename the StudyServer folder into StudyServerOld. Create new folder StudyServer. Move everything from StudyServerOld into the new StudyServer. Delete the StudyServerOld folder.

TEMP folders

In case an empty Study still does not compile, the location of system TEMP and TMP folders should be changed:

  1. Click Windows Start button.
  2. Click Control Panel.
  3. Click System, then select Advanced System Settings.
  4. Click Environment Variables, then in the User Variables window double click on the TEMP variable or select it and then click the Edit button.
  5. In the opened window, change Variable Value to C:\Windows\Temp and click OK.
  6. Double click on the TMP Variable or select it and then click the Edit button.
  7. In the opened window, change Variable Value to C:\Windows\Temp and click OK.


Run PowerLanguage, create a new study (any type) and try to compile it. It should be compiled without any errors.
