Flash Player not running when HTML files a loaded locally or from Network shares

[StephenHardy]

Hi All

 

Seeing an issue where when students/Staff/Admins/Local Admins attempt to run any HTML files with flash content in them from locally stored locations - flash refuses to work on our Windows 10 1709 clients.

 

Flash content on the web is fine, its just local files.

 

I've checked "Allow content to run in files on My Computer" is enabled, I've enabled all of the Active X controls in GPO & added the locations to my trusted sites list - still no joy. Very curious as it happens for the local admin account, Domain Admin accounts, staff & students.

 

Tried my hand at google fu but nothing really much out there (Tried added "EnableInsecureLocalWithFileSystem=1" to mms.cfg in x645 & x86 locations as per Local flash can't load in browsers) - any help would be greatfully appreciated.

 

 

Thanks all

We had this issue recently - I don't thin the fix was hard just needed some tweaking of URLs to load the content in a different way. I'll see if i can track down the ticket....

 

*****Edit*****

 

How are you opening the SWF files? When open in browser does the URL start with file:// or http:// ?

 

For us it looks like a switch from file:// to http:// on shortcuts solved the issue... I think.

Hi Thom

 

We are actually trying to preview from a link in Dreamweaver, but even just opening the file it doesn't like displaying the flash content at all.

 

Not able to change the switch to http:// as the files are local or on network drives using http:// will force a look out onto the net - unless I'm missing something?

 

 

Thanks

I'd just use it an excuse to get rid of soon-to-be-unsupported flash content.

But seriously, if the files are on a server, do you need to set your browser to "trust" the server?

I mean using the server name/shared folder name in the url in a browser. If you navigate to the folder containing the HTML file and then open with IE what is within the URL bar?

I've put the standalone flash player in a student accessible location, made it read only and they just file->open in it.

Issue is its local and server.

 

Adding the server to trust sites doesn't work as it would need to be file:\\ and you would need to specify the location for each share - these are students and therefore to deploy via GPO we would need to add every students area in as wildcards don't seem to be accepted, nor does simple paths to the local files we've copied for testing.

 

Flash is becoming obsolete but the students have completed their coursework in it and imported into Dreamweaver...

what happens when opening the html files to a browser and what is in the URL bar...

Turns out it was the way Dreamweaver CS3 was embedding the Flash content - CS6 is fine, the flash movie is fine embedded using DW CS6.

 

Checked the tags and they were all wrong in DW CS3

Sorry I meant to rely to this thread and totally forgot about it! Glad you found a fix
