Security programs such as anti-virus software and firewalls can interfere with Adobe Reader installations. According to Adobe, vendors such as Comodo, Jiangmin and Rising identify the Adobe Reader installation file as malware and block it. These programs report the file as a Trojan such as "TrojWare.Win32.Trojan.Agent.Gen" or "Trojan/JmGeneric.bcy." Temporarily disabling these programs before installation can solve the problem. In addition, updating security programs to new versions can also decrease the chance of running into such problems.
Adobe Reader is compatible with multiple operating systems, including Windows and Mac OS X, and browsers such as Internet Explorer, Firefox and Safari. Ordinarily, downloading and installing Adobe Reader takes minutes to complete; however, if the browser closes each time you try to download the program, one or more applications are likely interfering with the process.
If Adobe displays an error message such as "Metafile download failed" before closing unexpectedly when you try to install Reader, the issue is usually with proxy servers. If an error code or message pops up on the screen, entering the information on Adobe's website provides information about the errors and ways to solve the cause of the problem.
If you're still unable to download and install Adobe Reader, the link you're using may be the problem. In such cases, Adobe recommends using an alternative download link to install Reader. The direct download link (see Resources) requires you to select the operating system, language and version before installing the program. When the installation wizard pops up, follow the onscreen instructions to install Adobe Reader.
Tips and Recommendations
If one or more of the browser's files are damaged, it can freeze when you download content. Faulty browser add-ons can also cause downloading and installation problems. Therefore, if your browsing sessions continue to close unexpectedly when you try to download and install Adobe Reader, use a different browser.
