Great, I use APA or Cell, and I do not want the DOI number to show.

Please be certain that the publisher wants the _manuscript_ to be submitted without DOIs. Even if the journal article is printed without DOIs, reviewers of the manuscript need a simple path to viewing the cited references.

"An unexpected error occurred" when I tried to install the style on my second computer using the Standalone 5. What can I do about this?

Exactly the same way as I did it on my desktop computer where it worked.
I now tried both these methods without any luck
"double-click the downloaded file while Zotero Standalone is running to install it"
"CSL styles (with a “.csl” extension) can also be added through the Style Manager, found under the “Styles” tab of the “Cite” pane in the Zotero preferences panel"

Works now, thanks Adam!

Is there a specific journal looking for such a style? If not, it’s unlikely that more variant APA styles would be added to the repository. Particularly considering that the DOI is generally considered the single most important piece of information in the reference, as it (not volume, issue, or page number) uniquely identifies the reference and permits better citation tracking.

Looking at some papers, including one by yourself (Body Resposiveness Questionnaire - Benedek T Tihanyi et al), it uses DOIs.

Their author guidelines also point to examples using DOIs (e.g., Citation Machine). Please confirm directly with the journal that DOIs must be removed (include links to their other published papers including them) versus that they are simply optional.

we can't really make custom styles for everyone based on faculty whims -- are you sure you can't just use the version without issue numbers? APA style doesn't include issues for the majority of journals (all that number pages consecutively for an entire year).

DOIs are mandatory in APA style (as is, btw. omitting issue numbers for journals that are paginated by volume even though Zotero can't automate that).

Absolutely, you can hope that someone else will help you with your request.
When I say "we" I'm referring to the relatively small group of people who have both the skills and are willing to help with style requests. I know everyone who does this with any regularity, so I wanted to manage your expectations.

@getridodoi Although I find myself wondering if you are serious or simply writing outrageous things to troll; I will treat your comments as real.

DOIs do cost publishers but the cost is reasonable when you consider the computing infrastructure involved with making the DOI linking system operate quickly and robustly. Also, it is possible to obtain a DOI from certain entities at no or _very_ low cost. DOIs are a convenience -- a simple way to easily jump to a document online no matter where that document is stored. Before you become more emotional about you initial dislike of DOIs please do a little more research on the topic. I think your opinion will change when you achieve a better understanding of how the system works. There is no monopoly involved but there is an agreement among document creators and document distributors that in an ideal world there would be a single identifier that -- even if the publisher's website structure may change or even if the publisher itself changes -- will allow easy and direct access to the desired document.

If your school demands a non-standard citation style it shouldn't require great effort to edit your reference list as the last step before you turn in your report. Even if you have 100 references the time required to deleat theDOIs from every record might take 2 minutes.

If many students have the same style requirement you might consider pooling your resources to pay someone to adapt a custom style from APA6. The cost would be no more than US$150. Probably less--I have paid for complex custom styles and I've been pleased with the result. If you and your colleagues don't want to pay, you could learn to use the CSL style editor to make your own custom style. I have done this with simple changes to APA 6 and didn't need to stretch my dendrites too far. (I'm _not_ willing to do custom style work for your situation.) I understand your pain concerning an inflexable faculty member wanting her very own unique citation style. At my university the problem was colons, semicolons, and flavors of dashes.

Please also consider what was required to write a paper 25 to 30 years ago. When I was in college I had to find relevant references by examining annual printed indexes. I had to go to the library shelves and find printed copies of the journal articles before I would take detailed notes on index cards -- being careful to get all the metadata correct. It was common to be required to visit a second university library because the libraries wouldn't all subscribe to the same 2nd tier journals from every scientific discipline. I had to use a typewriter to type my paper. Formatting the body of the paper with citations was tedious. Serious errors might require retyping several pages to make a correction. There was no automation of the reference list. Everything was done by hand Very careful work was needed to format and punctuate each reference.

@getridofdoi

Did you actually see the 4th post in this thread? that's an APA style without the DOI.
You either now just add the issue in (super easy) or you do it the smart way and compare the two styles (standard APA vs the no-issue-no-doi APA) and adapt it accordingly....

As adamsmith stated, they are the single most important piece of modern references.

an opinion, btw., shared by the APA editors: http://blog.apastyle.org/apastyle/2014/07/how-to-use-the-new-doi-format-in-apa-style.html

APA doesn't use the word mandatory for anything, but on p. 11 of the APA Style Guide to Electronic References (published in 2012 as a supplement to the 6th edition of the manual) it unambiguously states:

Include the DOI in the reference if one is assigned

This is also in line with the editorial practice of APA journals (where bwiernik regularly publishes) and with direct communication with APA editorial staff. This is really not an open question.

As damnation points out above, you can customize citation styles all you want -- it's free software -- so go and implement your preferences as you please, just don't expect others to do it for you.

At this point you're wasting people's time and this is not a discussion forum but a tech support forum, so I suggest you leave it at this or at some point a moderator will decide you've wasted enough people's time.
