National Addiction & HIV Data Archive Program

I'm trying to download data, but I'm not getting any data files. Why can't I download data?

There are a number of problems that can pop up when you attempt to download data:

  1. You download a zipped file, but you don't get any data files...just the documentation.

    This means that we can't tell that you're part of a member institution, and the data you're attempting to download is only available to member institutions.

    This happens in four situations: 1) when you're trying to download data from home, but haven't downloaded from on campus in the last six months; 2) when you're trying to use a proxy server, but your settings are incorrect; 3) ICPSR simply doesn't have the complete IP range for your campus; and 4) the data that you are attempting to download are restricted from general dissemination (i.e., the data contain sensitive information and you have to fill out a lot of paperwork to obtain it).

    If you're downloading from home, read the information below on off-campus access. If you're using a proxy server, please stop; just go directly to our website. You'll know you're at a proxy address if the URL looks like http://www.myschool.edu.0-icpsr.umich.edu/ or the like.

    If the above suggestions don't apply, please follow the instructions in Helping ICPSR Troubleshoot below, and we'll attempt to fix the problem.

  2. You type in your login and password and get a message that you have successfully logged in, but are then sent back to the login screen.

    This generally means that you're not connecting to your proxy server properly. In this situation, you will need to talk to your OR or your local IT/networking staff. Please note that there is absolutely no reason to use a proxy server to access ICPSR data, and in many cases using a proxy server will interfere with downloads.

    If you're certain that you're not even using a proxy server, please follow the instructions below in "Helping ICPSR Troubleshoot".

  3. You get a message that states, "You have successfully authenticated but you are not authorized to access the requested document."

    Some sections of our website are only available to specific users. For example, some functions on the Official Representative (OR) website are only available to users whose MyData account has been flagged as an OR account. Or you have attempted to access an online analysis utility that is only available to member institutions.

    If you believe you have reached this message in error, please e-mail web-support@icpsr.umich.edu, and be sure to send them the URL of the page in question.

  4. You get an error message stating "...[your file] could not be saved, because the source file could not be read. Try again later, or contact the server administrator."

    This is an error that relates to Firefox/Mozilla. Please consult their documentation on the problem.

Helping ICPSR Troubleshoot

In order for ICPSR to investigate most access problems, we need to know your computer's network address, and we need to know what network address you're forwarding to us. To gather that info, do the following:

  1. Log in to MyData.

  2. Go to our ticket verification tool.

  3. Copy the text there and paste it into an e-mail to web-support@icpsr.umich.edu.

Downloading Data from Off-Campus

Assuming your OR has provided us with the IP ranges for your institution, you can access data from home, but you first have to login to the ICPSR website from on campus. Once you do so, your MyData account is validated for off campus downloads for the next six months. Every time you log in to the ICPSR website from on campus, that is extended another six months.

In the event that you simply cannot get on campus (for example, you're on sabbatical), simply contact netmail@icpsr.umich.edu. We'll check with your institution's Official Representative and then manually validate your account.
