Generic file I/O error. Cannot save VI "filename.VI"

Hi, I have LV 8.2. I am having problems saving VI's after editing them. I am getting the message:
Generic file I/O error. Cannot save VI "filename.VI"
I can recreate the problem by creating a blank VI, placing a property node on the block diagram, right clicking on property and choosing, select property and in the window that pops up expanding Application and clicking on Directory path and clicking OK. I save this VI to disk. Then I load the file again and delete the property node. Now if I try to save that I get: Generic file I/O error. Cannot save VI "filename.VI"
Furthermore with the real VI that I am having problems with. If, when I get the cannot save message, I do a "Save as" and save a copy as "filename backup" and then quit labview without saving the "filename" vi, when I run LabVIEW again I get:
The last time you ran LabVIEW, an internal rror or crash occured at save.cpp, line 821.
I click investigate internal error message now and get told there is a logfile of the error. The contents of the file on one occasion were, quote:

Any ideas?

Hello,
Sorry you've encountered this problem. The cpp error is a known issue, which is filed under corrective action request number : 42BI4OO5. In a nutshell, this means R&D is looking into the problem. I attempted to reproduce the problem as you described below, but I did not get the "Generic file I/O error" as you did.
If you have any further insight or detail which perhaps is the key to reproducing this, please repost, and I'll try to reproduce this again! In the mean time, does it help to copy and paste your code to a new VI, or does that VI suffer the same problem?
Thank you,
Best Regards,
JLS
PS -

Get Generic File I/O Error when running DAQ Reference Design

I Get a Generic File I/O Error when trying to Save Data to Disk in Data Acquisition Reference Design.lvproj from daq_ref_app_v10.zip in LabVIEW 9, If I configure to simulate one channel, start the acquisition, stop the acquisition and then save the data to disk, I get the generic file I/O and:
Error 6 occurred at TDMS Open in Data Acquisition Reference Design.lvlib:Logging [TDMS].lvlib:TDMS Data Logging.vi->Data Acquisition Reference Design.lvlib:Main.vi
Shouldn't this work without error?
Should NI distribute Reference Desgins that work without errors?
What is the problem with this application?

This error usually occurs because of malformed file paths. Put an indicator on the path before the TDMS Open so you can see the path explicitely. Make sure you have full permissions for the directory in which you will be saving and make sure that the path isn't greater than 255 characters.
Have a great day!

Access Privileges error, cannot save library

I have had my iPod for 4+ years but after upgrading software about a year ago, I repeatedly get the error "Cannot save Library. You do not have enough access privileges." I have followed recommendations in previous threads to unmark the read-only button but to no avail. Very frustrating. Please help before I switch to a Zune.

That error is referring to the iTunes Library.itl or .xml file, as explained in this article:
http://docs.info.apple.com/article.html?artnum=93732
WHen are you seeing this error, when you try to close itunes?
Can you rename that file? Because if you can't, the operating system is confused and thinks something has a lock on it. Restarting your PC should clear that situation.

V8.2.1: generic file i/o error while loading VI's

Hello,
I had a large LV application open and running fine. I closed it, and upon re-opening the top-level VI it gives "Generic File I/O Error" on several sub-VI's (belonging to me, not LV). Opening those sub VI's individually reveals no problem at all, and in any case the whole code base lives in a Subversion repository and I have tried checking out a fresh copy of the whole source code tree and the problem re-appeared. Before Labview displays the "File I/O error" it will hang for several minutes with no disk or CPU activity.
I just tried checking out a fresh copy of the source tree on a separate computer. Now Labview is hanging while loading "<vilib>:\DAQmx\create\channels.llb\DAQmx Create Channel (CI-GPS Timestamp).vi" after having managed to load 920 VI's. On edit: I spoke too soon. It is now duplicating the "Generic File I/O Error" on one of my sub VI's.
If anyone has any clue to this strange behavior please let me know.
Thank you,
-Brian

What I found was this...
My code calls a bunch of subVI's in another directory. Those subVI's in turn had some unwise paths saved in some of them that loaded other subVI's from a network shared drive instead of the local disk directory.
The network shared drive had been taken off line since the computer was delivered to a customer last Friday. When LV tried to load the VI's from the shared drive, it would hang for about 5 minutes, then give the "Generic File I/O Error" with an "Ok" button to continue. I eventually sat and did this for about 13 VI's, taking most of an hour while waiting for the network reads to timeout.
Once my now-broken application loaded I was able to successfully re-direct the missing VI's to the local disk, resolving the problem.
The "Generic File I/O Error" message could not be less useful in this case and I'm rather irritated by the genericity of the message. Something like "Network read failed" would have immediately illustrated the problem and kept me from wasting a whole lot of time deciphering it.

[Flat File Source [2]] Error: Cannot open the datafile "VendorPurchases20050512.txt".

hi
I'm trying to use foreachloop container in order to read the data that i have in several txt files and upload it into MRR table.
when i'm trying to run the package, i'm getting the following error:
[Flat File Source [2]] Warning: The system cannot find the file specified.
[Flat File Source [2]] Error: Cannot open the datafile "VendorPurchases20050512.txt".
[SSIS.Pipeline] Error: Flat File Source failed the pre-execute phase and returned error code 0xC020200E.
I don't know what's the problem since it was working before.In the flat file connection manager i defined all the path including the name of the file.
I'll be happy for assistance
thanks
Yaron

Hi Yaron,
Does the file stored in local file system or a share folder on remote server? If you can load data from a file in local computer, but cannot load data from a file in a remote computer, the issue may be caused by the Kerberos authentication. In this condition,
check the following points:
Enable SQL Server for Kerberos
Check delegation settings for SQL Server service account and Computer
Add Host SPNs for FileShare Server and SQL Server

Has your administrator had a chance to look into this yet? Backups do
need to respect databases better than just locking their files, it needs
to be a cooperative action.

How to resolve this error - "Cannot save the illustration The requested transformation would make.."

Hello Adobe Community,
I am trying to organize some album artwork within a pre-designed template and I keep getting this error when trying to save the file in the eps file format:
Cannot save the illustration The requested transformation would make some objects fall completely off the drawing area.
All the art is within the bleed lines. The only transformation I did was rotating one of the pieces 180 degrees. I'm not exactly sure what it is referring to when illustrator says objects are going to completely fall off the drawing area.
Your insights would be appreciated.
Thank you!
Chris

Did you use Guides at all? From the View menu, choose Guides>Clear Guides. Then zoom way out and do a Select All and see if there any stray points near the borders of the artboard. Direct select them and delete. Then try your transformation.

Error: Cannot save DataSource 3.x

Hi All, We are on BI 7.0 support pack 20. I am getting the below error while running the program RSTCC_ACTIVATEADMINCOCKPIT_NEW to intall/activate the Admin Cockpit.
Cannot save DataSource 3.x 0TCTBWOBJCT_ATTR(STG-010)
Message no. RSAOLTP077
Diagnosis
Cannot save DataSource 3.x (R3TR ISFS) on the database, since a DataSource (R3TR RSDS) already exists with the same name.
Procedure
If you want to recreate the DataSource, choose a different name.
Thanks!
Puneet

I tried restoring the DataSource from my ECC system and the error I received was:
Creation of DataSources for SAP source system

I clicked on the ? mark and recieved this following information
Creation of DataSources for SAP source system (SourceSystem) is not permitted
Message no. RSDS057
Diagnosis
You want to create a DataSource in a replicating source system (SAP source system, BI system, Myself system).
System Response
You cannot directly create DataSources for replicating source systems in BI.
The system terminates the process.
Procedure
Create the DataSources for the replicating source systems in the source system itself (SAP source system, BI system, Myself system) using Customizing Extractors (transaction SBIW).
When you replicate the DataSources to the BI system, the system displays them in theDataSource tree in the Data Warehousing Workbench.
I am getting the exact error as the original poster (Cannot Save DataSource 3.x) but am not able to resolve it. Any other ideas? when I say I try to restore the DS, I click on Create in RSDS

MS Excel Error - Cannot save file

Hello, I have a large Excel file (~130MB) that no longer permits me to save file... I receive error regarding not enough resources, but Excel is the only application open. Can you help? Note that the e-mail address used to login is no longer
valid. Thanks!

Hi,
Which Excel version and Excel file format are you using (Tip: If you are using XLS format, I recommend you convert it to XLSX format)?
Did the issue occur only in the special large file or the other small file?
As far as I know, the memory error messages can be very generic and don't always identify the real cause of the issue. However, if your file is large or contains a large amount of features, it is possible you are running low on available memory resources.
Then, we may try to follow the provided methods in this article to troubleshoot the issue:

External hardrive error, cannot save files onto ex hd, NEW MAC USER!!! D:

hello, i just recently purchased my macbook pro last night, and i had no problem adding all my songs into itunes from my western digital harddrive. But one problem i have been starting to notice is that i can't save any files on it. And whenever i plug it in, it tells me that there has been an error trying to open it up. I have googled for a few hours and the only solutions i have seen are that the cord may be too long and i need a new cord or i have to reformat it, which i don't want to do or else my thousands of songs and pictures are gone. What is the best solution to get access to save to my hard drive without causing any damage to my files. Thank You!

on the step where you have to use terminal, after UUID, it only says:
Display detailed information about a disk or partition.
Root access is not required.
have i done something wrong?
edit*-after googling, i see that i should have had a number sequence pop up, ill try again now

Illustrator cs5 can't saved the file or unknown error when save

Hello,
I have couple of brand new Mac OS X 10.6.4 with Adobe Ilustrator CS5 running on Intel Xeon Quad Core and 3GB of RAM.
All updates including OS have been applied recently. For some reasons, the file that was worked on any of this computer can't be saved to any other format other than illustrator template itself. When saved, it either just crashed or gave an error "an unknown error has occured".
So, I save the file as template and tested on the PC configure that has 8GB of RAM, Intel Quad Core and still couldn't save the file into .ai format. Same error was given.
I tested the illustrator on mac with few simple lines or vector graphics and it could save fine.
I thought it was the file itself but it appeared to be not. Due to, same design method was produced on the old mac os system with cs2 worked fine.
Does anyone know what is wrong? I called the Adobe techs and they transfered me to someone in India who didn't know what causing it either.

Also, I tried to reset the prefs and settings, uninstall with cleaner tool and reinstall, reload the transparent setting, etc.. including some steps the adobe techs told me.
It still gave same error.

Strange error: cannot save jpg

I have a very strange problem with a jpg image. it's an RGB thumbnail of 135 pixels x 117 pixels.
I open an existing jpg.
I paste something in the image and flatten it...
then I try to save it under a new name but it will not save and give the following error: Could not save (pathname) because of a program error.
now the strange thing is: if I do an image size to 134 x 116 pixels. (or 136 x 118) the image saves fine!
If I then resize it back to 135 x 117 pixels...it won't save anymore and the error is back.
if I don't flatten the image.. i can also save it as a jpg. If I flatten the image and try to save: the error is back.
I can save other images as jpg without any problems.
any idea what may cause this?
(I use Photoshop CC on windows 8.1)

I've run into the same issue here...not all the time, but when it happens, it's easily replicable as soon as I paste as a new layer then flatten. Of course, today, I can't get it to misbehave.
The only workaround I figured out was to copy the whole flattened image and create a new document, which I was then able to save.
The only thing I can think of is that my Mac is bound to an Active Directory, so it's logged in as a "mobile" account. I know this caused permissions problems in previous versions.

Error -50 : unknown error - cannot save library

Hello everybody,
I recently changed from windows 7 pc to windows 8 pc and I have installed the most recent version of iTunes (11.0.4.4). However, when ever I start up iTunes I get an error message that iTunes can't save library; unknow error -50. I googled on the internet for solutions. The most solutions were from years ago and not specific for windows 7. So until know nothing solved my problem. I cant imagine that I am the only one having this problem. Therefore I kinda was hoping that one of you fellow iTunes enthousiatic users has or had the same problem and can help me solving it.
Before you all redirect me to another similar threat on this forum; I have seen it and I have readt it. And I tried the suggestions. And they didn't work. And I noticed that all the answers and suggestion were for Mac OS users. I use Windows 8 ! So I was hoping that someone could suggest solutions for Windows 8 users.
Thanks a lot in advance.
Frank

The error has been addressed in the latest iTunes version 7.3.1

Failed export to Excel PDF files contain XFA forms cannot save in specified format

Has this excercise been a waste in time and money. Like my car I will put petrol oil water and air where they need to go but don't care how they make the car work as long as it goes

Converting forms to fill them in is never a good idea; if they are official forms it can be a catastrophe. Keep the forms as PDF, don't convert.
XFA forms are ALREADY FILLABLE. If you can't fill it there is a fault.
