   • Do NOT check the box "Remove MultiCharts user data from computer", leave it clear

6. Close MultiCharts.
7. Make sure all MultiCharts Processes are ended in the Windows Task Manager.
8. 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).
9. Restart MultiCharts.

If your MultiCharts version is below 8.8 and you are uangle 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.

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. If the issue persists, please contact our support team in [Live Chat].
