Adobe Premier CS 5.5 Trial won't open. Invalid checksum

program downloaded, go to open and comes up invalid checksum. Nothing opens. Note: the download assistant kept trying to Extract for hours before this. Would never stop spinning.

Re-download. Invalid checksums mean the archive is damaged. Before downloading again, make sure your harrdrive is okay by running fcheck/ Disk Utility, defragmenting it etc. Also make any security tools behave. Deep-scanning archives by virus scanners may sometimes damage them.

.dmg file won't open, invalid checksum

Hi there -
I'm downloading the CS6 Master Collection trial via the Adobe Download Assistant onto a Mac running OS 10.7.4. When I try to open the .dmg file, I get the warning:
The following disk images couldn't be opened
MasterCollection_CS6_LS16.dmg, invalid checksum
If this helps, the download bar in the Assistant says "Extracting... this may take a while." It's been like that for about three hours.
Do I need to re-download? It took ~24hrs, so if I don't have to, I'd rather not.
Thanks!

I tried to do that as I first downloaded it from Firefox, then Safari, like you said to, but I got a message saying that "This product is already in the queue and will be not be added (error 105). If you believe you have received this message in error, you can restart Adobe Download Assistant and try to add the product again".
I have already tried this four times, I even "Force Quit" ADA to clear the queue, but whenever I click on the download button on the Adobe website, I keep getting the same message.
This only started because I had the same error as the original post.

Can anyone provide the link to download Adobe Premier Elements as a trial version? Many thanks.

Adobe Reader is shutting down and won't open

Adobe Reader is shutting down and won't open, can i get some support?

Some things to try...
Using Windows Explorer navigate to C:\Program Files (x86)\Adobe\Reader 11.0\Reader, then double-click on Eula.exe and accept the license agreement
Can you open Adobe Reader by itself? If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].
It could even be a malware issue; see http://helpx.adobe.com/acrobat/kb/reader-core-dll-error.html

Since the recent upgrade from Adobe pdf plug-inn Firefox often won't open pdf-files. Uninstalling doesn't help. I don't have this problem with Internet Explorer.

Hi efacg,
Most printing issues are solved by resetting the Printing preferences. When you print from Firefox and you click on the down arrow, do you see Defualt and Firefox? Please make changes to the preferences here and preview the document.
If this continues to be an issue please also see [[Fix printing problems in Firefox]]
If there are any other questions, please do not hesitate to ask, we are here to help.

I have Windows 8.1 and Adobe CS6 - acrobat just stoped working, won't open anything won't print to pdf. HELP!

Please help me!! I have Windows 8.1 and Adobe CS6 creative Suite. Adobe Acrobat x just quit, It won't open anything and it wont print to PDF. I need this for work!

Typically, the repair is done from the Control Panel>Programs & Features. In the future, try that route. Glad you found something that worked. When you do come to the forums for help, you may not get an immediate response, but may have to wait for someone familiar with your issue happens to check the forum, possibly after work. In any case, glad you have a working product again.

Adobe Acrobat XI Pro free trial won't launch, claiming no Internet connection

Hi,
I wondered if anyone could help me solve this mystery: I am trying to launch the Adobe Acrobat XI Pro free trial. Sign In is required to use the trial. But when I click on "Sign in now", I get the message "Please connect to the Internet and retry". Which is strange, because my Internet connection is active and stable. The same panel hints that my clock might be at fault (but it is correct). I am running Windows 7, no earlier version of Adobe Acrobat installed. I would greatly appreciate any suggestions you might have on how I can resolve this riddle.
Thanks in advance,
Andreas

Hi SumitV,
Thank you for answering and suggesting ways to remedy my problem. I tried all the four actions you made me aware of, but although everything seems to be all right, I still cannot launch Acrobat XI in the trial version. The only little hickup came when accessing Adobe's secure site, which prompted this message:
But when I later checked the certificate, it seemed to be installed and enabled. I am no expert, but it looked like it should according to step 4 under http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-i ssues.html

A3D trial won't open

Hello all. I downloaded the trial version and it appeared to completely install and place the icons on the desktop screen. But the program won't open when I click to start. The hourglass appears when I click but stops after several seconds and nothing happens after that. There's plenty of memory available on my C drive (15 more gig's) and 512 meg of RAM. I had previously run the trial of Adobe Acrobat 7 Pro-----but that and my version 5 were uninstalled prior to downloading the A3D trial. Could my previous trial on 7 Pro be blocking me out of this new trial??? I have run virus scans, disk cleanup, defrag and restarts. Computer is a fairly new Sony VGN-A190 laptop running XP home edition with service PAK 2. All other programs and functions seem to be normal.

I can not believe this!
I do have the same problem!
I do have to format my hard disk to get this bulls.... of my system?
Adobe wants to sell a product for a over $1000 and says "thank you" if it does not work because it is buggy "this now cost you some thousand Dollar to rebuild your system"
That can not be true! There has to be somebody with a feeling for decency in bussines how is willing to help here!
Please!!!!

Adobe Classroom in a book file won't open anymore

I have a Framemaker 7 Classroom in a book file that won't open anymore. I purchased in in 2006
and it's worked for years. There is no error message. I keep getting redirected to Adobe Digital Editions website. So I've installed the Adobe Digital Editions software and still no luck. I spent 2 hours on the phone this morning with Adobe support and their final conclusion is they don't support this issue.
Anyone have any ideas? All my other pdf's open with out any trouble. Some of them are ancient.
Thanks,
June

InDesign Mac Trial Won't Open

Hi, I was attempting a Mac trial of InDesign, but it won't open without crashing. I deleted and re-downloaded and installed, but it still won't open. Just crashes after attempting to open. Can you help me?

We're seeing quite a few reports that the installer is failing to set the permissions correctly on the preference folders. Log in with a new user on the Mac and see if ID will launch.

Adobe Premier Elements 13 - Free Trial "Download Completed" but nothing else is happening?

I downloaded the free trial version, but it is stuck at "Download Completed" and not doing anything else after that.

Yes. I also tried to open the Setup, but that suggests restarting my computer and downloading the trial all over again... I've done that twice without success.

Trial won't open and neither will my account

I recently downloaded the trial for photoshop but it refuses to open. I had no probelms with the download but every time I try opening the program its tells me that I need to renew my subscription, and this is based on the adobe account of the previous laptop owner. It does give me the option to sign in to my account, but everytime I sign in it redirects me to a serial number screen. I've deleted all the previous adobe programs under the previous owner's account but that did not help at all, it still tells me the same thing. I am obviously missing something here. Any help would be much appreciated.

This won't work. You cannot have a trial and the same product serialized at the same time. Even flushing out the activation data as explained here won't help, as the encrypted activation keys are stil lstored on your system. Sorry, but short of reinstalling your operating system wit ha full format of the drive there is no realistic way that this will ever work.

Adobe Premiere Pro CC 2014.1 won't open and crashes

Hi all,
I'm pretty desperate because I need to work on a project by my colleague (who works with Premiere, latest version)... but I just can't make my version even open. As soon as it starts firing up, it crashes.
I used to have a working version (7.02), but with this I could not open his project (from 8.1)... and hence downloaded the newer version. I de-installed it again, hoping that it might have just been an installation bug... but sad irony... no version works anymore. I have "rented" my premiere from "the cloud", however all I can get to download now is the trial version. I wouldn't mind that... if it only worked... because I'm on a tight schedule.
So here are my specs:
Model: MacBookPro10,1, BootROM MBP101.00EE.B02, 4 processors, Intel Core i7, 2.6 GHz, 16 GB, SMC 2.3f36
Graphics: Intel HD Graphics 4000, Intel HD Graphics 4000, Built-In
Graphics: NVIDIA GeForce GT 650M, NVIDIA GeForce GT 650M, PCIe, 1024 MB
I would be grateful for any help - until a month ago... I "only" worked with the MC... and hence I'm new bee in adobe land.
Regards and THANKS
Christina

Dear all,
thanks for your help! I was able to talk to a very professional and understanding member of Adobe support and the source of the problem was more banal:
Since updating to OS X 10.9.5 all my permissions were a mess. Premiere wasn't allowed to "read and write", and hence unable to create folders etc - although the boxes were all ticked in the right way. However after the permissions were restored (and there were loads of faulty ones)... premiere seems to work again fine!
So what I got out of this is to be very careful before updating my system again... -> "never change a winning team" -> however not updating for ages can't be the solution too... I will have to find the right balance ;-)
Again: Thanks for all your advice... in any case I've learned lots by trying out your different suggestions
Christina

InDesign CC Trial won't open files

I have been using the trial for about 2 weeks. We work on files off a server at work, and our server went down today. This caused InDesign to crash and when I reopened it, it would no longer open any files. These are files I created using the trial and was just working on earlier today, and now I get the message "Cannot open the file xxxxx. Adobe Indesign may not support the file format, a plug-in that supports the file format may be missing, or the file may be open in another application."
I have already tried the following:
Restarted my computer
Restarted InDesign
Ran Creative Cloud updates
Uninstalled and reinstalled InDesign CC trial
Had a coworker open the files on his CC trial (worked fine)
Can anyone help?
