Error Code 1603 Fatal Error During Camtasia Installation


The Camtasia installation fails with the error "Error Code: (1603) Fatal error during installation."



Before proceeding, make sure that all Windows updates are installed. See this Microsoft support article for instructions on how to check for updates. 

Option 1: Reboot and Run as Administrator

  1. Reboot the computer.
  2. Right-click on the installer file and choose Run as administrator.

Option 2: Silent Install

  1. Download the MSI installer for the version of Camtasia you are trying to install. The MSI can be downloaded from our Downloads Page by selecting the version from the dropdown, then click the MSI download link.

  2. Press Windows+R on your keyboard to open the Windows Run window.
  3. Click Browse.


  4. Click All Files.


  5. Browse to where the MSI (from step 1) was downloaded to. Select the MSI and click Open.
  6. At the end of the path in the Run window, add: /qb /l*v log.txt


    If the MSI were saved to the Downloads folder, the command would look like: C:\Users\%username%\Downloads\camtasia.msi /qb /l*v log.txt

  7. Click OK.
  8. Camtasia should begin to install. Once the installer window disappears, check to see if Camtasia has installed successfully.


If there is still an error or if Camtasia is not installed, please submit a support ticket and include the log.txt file from Option 2 (above) in your ticket. The log.txt file will be in the same location as the MSI file on the computer.

Option 3: Temporarily Disable Bitdender

We have seen from working with some customers that the Bitdefender program can cause this error to occur during installation.  We found that if we temporarily stopped Bitdefender from running, installed Camtasia, then resumed Bitdefender, that allowed the install to be successful.
