If you uninstall BioStar 2 and reinstall it after you have to use the cloud setting in BioStar 2, you will not be able to use the same subdomain name. However, if you back up the setting.conf file and overwrite the file in your new installation, you should be able to reuse the subdomain name.

1. Open File Explorer in Windows.
2. Go to the BioStar2 Installation folder as shown below and find the file: setting.conf

• In case of installed BioStar 2 for 32bit: C:\Program Files (x86)\BioStar 2
• In case of installed BioStar 2 for 64bit: C:\Program Files\BioStar 2\BioStar 2(x64)
  

3. Right click on the file and click Open.


4. Select Select a program form a list of installed programs and click OK.
5. Choose Notepad (or any other text related software) and click OK.
6. Copy the cloud related information shown below and save it in another notepad file to be safe.


7. Uninstall BioStar 2.
8. Reinstall BioStar 2.
9. Open the new setting.conf file at the same location as before.
10. Paste the copied information within the cloud {} and save.
11. Go to BioStar 2 > Setting > Cloud. You should be able to use the same sub-domain name you used before.
