An unknown error has occurred in processing the license. [SAK1053-1202]

To run the game please execute the startup.exe file and then enter your DLsite English account username and password into the respective text fields.

If the error occurs when executing the startup.exe file, there is a possibility that the file is being intercepted by your security-related software. Please confirm whether temporarily turning off the firewall settings of Windows and other security-related software resolves the issue.

●If authentication fails

First and foremost, updating Windows OS to the latest version may solve the problem. Please refer to [ Microsoft's page ] regarding Windows Update.

1. Make sure that you have admin access.
   To run the decoding tool, you be logged into your PC as an Administrator.
2. Protected files may not work unless you turn off other programs running in the background: WinAmp, Image viewer, TV recorder, file cleaner, capturing software, and especially security software.
   If the following processes are running on your PC, please end them.
   ・TeamViewer_Service.exe
   ・LogMeIn.exe
   ・DropBox.exe
   ・OneDrive.exe 
3. Please try placing the product data directly under your local disk (e.g. C:) to view / execute that product. Placing files in a location with a long path can sometimes prevent　them from starting and functioning normally.
4. Make sure that the downloaded file has the same size as listed on the product information page. When extracting, please right-click on the file and choose "Extract" or "Extract all." When extraction is finished, please do not double-click the product file in the extracted folder. Instead, right-click on the file and choose "Run as administrator".

It will 100% not work in a virtual environment, or with remote desktop connectivity active. If you are running your OS virtually or have software like TeamViewer running you simply cannot.

For more details about the user authorization system, please refer to related information.

●If the above does not solve the problem

You might need to change your PC's configuration. Please follow the steps below.

・Data Execution Prevention (DEP) settings

1. Right-click on My Computer and choose Properties.
2. Go to Advanced tab > Performance > Settings.
3. Go to Data Execution Prevention tab in Performance Options window.
4. Check the box of Turn on DEP for all programs and services except those I select:
5. Click Add and choose the program .exe (the product file you downloaded and tried to start).

It is also possible that it is a compatibility issue.
In such a case, changing the application file's settings may solve the problem.

・Application file's compatibility settings

1. Right-click the startup.exe file and choose Properties
2. Check the Run this program in compatibility mode box in the Compatibility tab and choose Windows XP (Service Pack XX)
3. Click Apply and OK.
4. Try executing startup.exe file again.

●Security Application

Again... There is also a possibility that a file being is intercepted by your security-related software. If all else fails you may wish to try turning off temporarily the firewall settings of Windows and other security-related software when downloading, extracting and executing the file, or setting an exception rule for the product folder/file.

We have received several reports regarding incompatibility between anti-virus software and Japanese fonts in some products, especially when it is a game in software format.

Protection software related issues are usually solved by turning off the anti-virus software, other security software and also firewall settings on your computer.

●If the product still does not work

If even after that performing all the above steps, the product still does not work, please finally confirm that the following folders actually exist and also try setting an exception rule for them in your anti virus software / firewall settings for Windows (or otherwise).

C:Program Files (x86)Common FilesCypherTec
C:Program FilesCommon FilesCypherTec

These folders contain files which are necessary for the authentication system to work and they should automatically be created upon running the protection software.

●If none of the above steps solves the problem

1. Please download and unzip [ this file ].
2. Please run the "ctmov_unreg.reg" file. Please select "Yes" when a new window appears. (The window will appear twice)
3. Please restart your PC.
4. After restarting your PC, please try running the software.
