Thank you for your continued support of Pegasys products.

We are currently experiencing an issue with some of our products (prior to August 2021) that the application does not start due to the error "The executable file is different from the original".

The cause is as follows:
The "VeriSign Class 3 Public Primary Certification Authority - G5" digital certificate used in the applications has been revoked for some reason.

We are currently confirming the possibility of restoration. And we will inform you separately as to whether the restoration is possible or not.

(Updated: Aug. 25, 2023)
The revocation of said certificate has been cancelled, and we have confirmed the affected products start up properly.

We sincerely apologize for any inconvenience this may have caused.
