When pdffactroy and Adobe Acrobat are installed on some ghost XP versions, you will be prompted that the virtual printer cannot be installed because a module is missing.

Reprinted: http://see.xidian.edu.cn/news/200810/20081022133530.htm PS: My system is deepin xplite version. I used to install a pdfcreator software. This software also installs a PDF virtual printer driver. As a result, an error message is displayed during installation, after printing the document, I couldn't find the printer. After reading this article, I finally knew what was going on. However, it seems that deepin XP lite versions cannot use such software to install virtual Printer Drivers (because I have not fixed the "System Restoration" function, huh, huh) In some ghost versions of XP, when pdffactroy and Adobe Acrobat are installed, a message is displayed that a virtual printer cannot be installed because a module is missing. (Editor's netfairy note: the details are as follows: If Adobe Acrobat is installed, the system prompts "Warning 20225: Adobe Acrobat 7.0 installer cannot create a new key object: Adobe PDF converter. Adobe PDF printer may be unavailable. Getlasterror: the specified module cannot be found ". If pdffacloud is installed, the system prompts "pdffacloud pro cannot be installed (addprinterdriver failed)... the specified module cannot be found ".) This is not because the Print Spooler service is not started or because the environment variable patch is changed by other software. (Indeed, I started the Print Spooler service) The real reason is that XP's original "System Restoration" function has been reduced !!! Many people may not think of the connection between a virtual printer and System Restoration, but this is the case. (How to check whether the system restore function is simplified: start or stop "system restore service" in "service". If the system cannot be started because a file is missing, it indicates that the system restoration function has been reduced .) To reinstall the System Restoration function, find \ windows \ INF \ Sr. inf, right-click and select "Install", follow the system prompts to install the function, and then restart the system. (Editor netfairy Note: At this time, the system prompts you to insert a WINXP installation disk. Please prepare the disc or ISO virtual image in advance) After the system restoration function is successfully installed, install the pdffactroy and Adobe Acrobat virtual printers. This method is successfully tested on the "ghost Windows XP Professional SP2 20061111 NTFS" version. (This version simplifies the System Restoration function, and the author is very low-key, if the system does not have a name or contact method, it is not easy to find him ). I don't know if this method works for the previous deepin system. I cannot test the deepin system because I have no deepin system to install a virtual printer.
