“Adobe Shockwave Flash Crashed”, You may be noticed this message randomly when using VMware vSphere Web Client but it is not the case now. When I try to open vSphere Web Client using Google Chrome, I noticed this message continuously even after multiple attempts in Google Chrome and in Mozilla Firefox. Looks all my Colleagues also facing the same issue. I suspect this could be some of the patch updates either with the browser or Adobe Flash. Since vSphere Web Client is crashing in both Google Chrome and Mozilla Firefox. Did a quick search in google and twitter, looks most of the people are facing the same issue. Found the VMware KB states that This is a known issue with Adobe Shockwave Flash version 220.127.116.11, and affects all versions of the vSphere Web Client and also provided workarounds to get rid of this error “Adobe Shockwave Flash Crashed” while using vSphere Web Client. Even though VMware Provided KB for this, I would like to write a quick note to my readers with a step by step procedure to workaround this issue in this article.
5 Workaround for “Adobe Shockwave Flash Crashed” with vSphere Web Client
1. Access vCenter Server using VMware HTML5 based vSphere Client
HTML5 based vSphere client was available with fling in an earlier version and VMware made it available with vSphere from vSphere 6.5 GA and later. You can access the vCenter server using HTML5 based vSphere Client Which does not depend on Adobe Flash.
Since VMware also decides to depreciate the flash based vSphere web client in the next numbered release (not Update release but with next major release of vSphere), I would recommend getting familiar with HTML5 based vSphere Client. Take a look at my article Worried of Web Client, say Good bye to vSphere web Client!!! to read more about vSphere Web Client Depreciation plan
HTML5 based vSphere client initially released with the limited features and tasks to perform. With the release of vSphere 6.5 update 1, almost 90% of tasks can be performed via HTML5 based vSphere client. Take a look at my article What’s new with vSphere 6.5 Update 1 to understand latest features of vSphere 6.5 Update 1.
To access vCenter Server using HTML5 based vSphere Client, Simply type https://<vcenter-server-hostname-or-IP -address> and Click on vSphere Client (HTML 5) to access vCenter using HTML5 vSphere Client.
You can directly access the HTML5 vSphere Client using https://<vcenter-server-hostname-or-IP -address>/ui
2. Access vCenter Server using Windows based vSphere Client (C#)
If you are using vCenter Server 6.0 and below, you can access your vCenter Server using Windows based vSphere Client. Windows based vSphere Client (C#) cannot be used to access vCenter 6.5.
3. Access vSphere Web Client using Internet Explorer
