Error code 126663 is a file-opening error in the Vectric software suite, indicating that the file was created using a pirated version of the program and cannot be opened in a legitimate version. To resolve this, the user must obtain a legitimate version of the software and create a new file, or, if possible, have the sender recreate it using the official software. 

Cause of the error

  • Pirated software: The error message “fail to open file” is a direct result of the file being created with an unauthorized or “cracked” version of Vectric software.
  • Incompatibility: Files from pirated versions are not compatible with legitimate copies of the software due to version discrepancies and security measures. 

What to do

Note on third-party sellers: Be wary of purchasing software from third-party sellers on marketplaces like eBay, as they are often selling pirated versions that will cause this error. 

Obtain legitimate software: Purchase and install a genuine copy of the Vectric software to avoid this error in the future.

Have the file recreated: Ask the person who sent the file to recreate it using a legitimate version of the software and send it to you again.
